How to Dual Boot Chrome OS and Windows 10 (Supports Play Store)

We have already written a dedicated article on how to install Chrome OS on PC, but many users are looking to run Chrome OS and Windows 10 side by side. And that’s why we have brought this detailed tutorial on how to dual boot Chrome OS and Windows 10. It will allow you to have the fast performance of Chrome OS and the versatility of Windows 10 side by side. Not to mention, there is support for Play Store and Linux apps as well. Basically, the confluence of Chrome OS and Windows 10 is a win-win combination for users. So without further ado, let’s go ahead and learn how to install Chrome OS and Windows 10 on a single machine.

Dual Boot Chrome OS and Windows 10 (Updated February 2021)

Before we go ahead, I want to make it clear that the tutorial is quite technical in nature so proceed only if you are well-versed with operating multiple systems. Apart from that, this tutorial will not touch any of your Windows files, but as a matter of precaution, you should back up all your important files. One never knows when things go south. Finally, I would recommend you to go through the guide step by step and for that, we have created multiple sections for easier navigation.


  • UEFI support in the motherboard
  • Support for legacy BIOS has also been added, but there are a few limitations. You can read the documentation here.
  • Intel-based CPU and GPU
  • Support for AMD CPU and GPU has also been added, but currently, it only supports AMD Ryzen 3XXX and AMD Stoney Ridge processors
  • A USB flash drive with at least 16GB of storage space


1. First off, download the Linux Mint Cinnamon image. You can also use other Linux distros such as Ubuntu or Debian, but since Linux Mint is pretty lightweight, I am using it in this tutorial.

2. Next, download Rufus (Free) so that we can flash Linux Mint Cinnamon on the USB drive.

3. After that, download the official Chrome OS recovery image from here. If this link is not working then you can download the image from here as well. Open the website and search for “rammus”. Now, click on the latest recovery image to download it (right now it’s 87, but it may change in the future). Here, I am recommending “rammus” because it works on modern Intel processors. However, you should follow the below rule and download the specific image based on your processor.

  • “rammus” is the recommended image for devices with 4th generation Intel CPU and newer.
  • “samus” is the recommended image for devices with 3rd generation Intel CPU and older.
  • “zork” is the image to use for AMD Ryzen 3XXX.
  • “grunt” is the image to use for AMD Stoney Ridge.

4. Now, download the most important file: Brunch. It’s a framework built by a developer named sebanc so huge thanks to him for making this project possible. The framework creates a generic Chrome OS image from the official recovery image so it can be installed on any Windows PC. To download the file, click here and look for the latest stable build and then click on “Assets”. Now, download the “tar.gz” file.

5. Finally, download the “” script which magically installs Chrome OS on a Windows partition. The script has been written by Kedar Nimbalkar. To download it, click here and press Ctrl + S to save the file. If the above link is not working then you can click on this alternative link to download the “” script.

Now that we are done with the downloads, let’s jump to the steps, shall we?

Manage Files

1. First of all, create a folder named “Chrome OS” on a drive that has ample space. After that, move the “” file to the “Chrome OS” folder.

2. Next, right-click on the Brunch file and choose “Extract to Brunch…”. All the files will be extracted in a folder.

3. Now, move all the extracted Brunch files to the same “Chrome OS” folder.

4. Similarly, extract the official Chrome OS recovery image and you will get a folder on the desktop. Open it and rename the file to rammus_recovery.bin. If you have downloaded another image then rename it accordingly. For example, if you have downloaded the “samus” image then rename it to samus_recovery.bin.

5. Finally, move the “rammus_recovery.bin” file to the “Chrome OS” folder. By the end, you should have these 6 files inside the “Chrome OS” folder. Make a note of where you have kept the “Chrome OS” folder.

Create Partition

You need to create an “Unallocated” partition on Windows 10 which should at least have 14GB or more space. I have provided 100GB of space, but you can choose your own partition size. Having said that, make sure to follow these rules so that you don’t encounter errors during the installation process.

  • Make sure the Chrome OS partition (unallocated) size is less than the drive where you have stored the Chrome OS folder. For example, I have stored the Chrome OS folder in the C drive which has 120GB of free space so I assigned 100GB to the Chrome OS partition.
  • Although I have created a 100GB partition in this tutorial, I would recommend you to assign partition size in this fashion: the partition size should be divisible by 11. For example, 99000MB (99GB), 88000MB (88GB), 77000MB (77GB) and so on. I know this sounds weird, but it has worked for many users.

1. Press the Windows key once and search for “disk partition“. Now, click on the first result.

2. Here, right-click on the last drive and select “Shrink Volume”.

3. Now, enter 102400 MB which equals 100 GB or whatever your preferred size is (must be above 14GB). After that, click on “Shrink“.

4. You have successfully created an “Unallocated” partition. In the next few steps, you will be installing Chrome OS to this unallocated partition.

Flash Linux Mint Cinnamon

1. Connect your USB flash drive and open Rufus. Next, click on the “Select” button and choose the Linux Mint Cinnamon ISO image. Now, just click on “Start”. You will get a few prompts so click on “Yes” and “OK” to continue the flashing process.

2. After Rufus is done with flashing, close it. Now, plug the USB flash drive into the PC on which you want to install Chrome OS. If you are installing Chrome OS on the same PC then keep it plugged in.

3. Next, restart your PC and press the boot key continuously to boot into the UEFI/BIOS menu. If you don’t know the boot key of your PC then you can find it from the below table.

4. Once you have entered the BIOS, move to the “Boot” tab and select “UEFI” from the Boot List Option. If this option is not available then don’t worry, move to the next step.

5. After that, move to the “Security” tab and disable “Secure Boot”. Keep in mind, every BIOS has its own interface so the menu placement might differ from one PC to another. Nevertheless, look for “UEFI” and “Secure Boot” under Security, Boot, or System Configuration tabs and make the changes accordingly. Keep in mind, disabling Secure Boot is mandatory.

6. Finally, move to the “Exit” tab and choose “Exit Save Changes“. Immediately, after that, start pressing the boot key again. You will be asked to choose your boot device. Select the “USB drive” and hit enter.

7. You will boot straight into Linux Mint Cinnamon. If you are prompted with a splash screen, choose the default option: “Start Linux Mint“.

Install Chrome OS

1. Now that you have booted into Linux Mint, click on the network icon at the bottom-right corner and connect to WiFi or Ethernet. The Chrome OS installer will need an active internet connection to download some necessary libraries and dependencies.

2. Now, open “Computer” on the desktop and move to the drive where you have stored the “Chrome OS folder“.

3. Here, right-click anywhere on the window and open Terminal. Now, type sudo sh and hit enter.

Note: If you are getting “read-only” or any kind of error then head over to the Troubleshoot section for help.

4. It will start downloading the necessary libraries. After that, a GParted window will automatically open up. Here, scroll down and select the “unallocated” partition (100GB). After that, click on the “Plus” button at the top menu bar.

5. Next, choose “ntfs” as the file system and click on “Add”.

6. After that, click on the “Done” button at the top menu-bar.

7. Next, click on the “Apply” button.

8. Now, make a note of partition number which starts with “sda”. For instance, mine is sda9. Finally, close the GParted window.

9. On the Terminal window, enter the partition number that you noted above and hit enter.

10. It will show you the partition detail and will ask for your confirmation. If the partition selection is correct, type yes and hit enter.

Note: If you face any error then go through the Troubleshoot section to find the solution.

11. Finally, Linux Mint will start installing Chrome OS on your Windows partition.

12. After the installation is complete, on the Terminal window, scroll up a bit and you will find a “menuentry” section. Now, select whatever is inside the “menuentry” section and copy it. You can right-click on the Terminal window to copy it.

13. Open “Computer” from the desktop again and move to C drive or any other Windows partition. Right-click and select New Document -> Empty document. Here, add .txt at the end and save it.

14. Now, open the text file and paste the commands that you copied from the terminal window. After that, save the text file.

15. You are finally done with the installation. Now, click on the start menu of Linux Mint and restart your computer. Immediately after that, remove the USB drive and you will boot directly into Windows 10 as we have one more step to do.

Dual Boot Chrome OS and Windows 10

You have successfully installed Chrome OS on a Windows partition, but you need to add Chrome OS as a bootable OS during the startup. And for that, we will use the Grub2Win application.

1. Boot into Windows 10 and download Grub2Win (Free) application. Keep in mind, the application is slightly slow so keep patience while handling it. If Grub2Win is not working then you can try EasyUEFI (Free trial for 15 days) as well.

2. During the setup on Grub2Win, keep everything as default and move forward. After that, click on “Manage Boot Menu“.

3. Here, click on “Add a New Entry“.

4. From the drop-down menu, select “submenu” and type “Chrome OS” under the Title field. Next, click on “Edit Custom Code“.

5. Here, paste the command that you copied from the Terminal and saved it in a text file. It should start with “img_part” and make sure there is no “}” at the end. Now, click on “Apply” and “OK”.

6. You have successfully added Chrome OS to the boot menu along with Windows 10. You can also move Chrome OS to the top by clicking on the “arrow” icon. Finally, click on “Apply”.

7. Now, restart your computer, and this time, you would find both Chrome OS and Windows 10 in a Grub2Win interface. Select “Chrome OS” and it will take some time to set up everything on the first run.

Note: If the Grub2Win interface is not showing up after a few bootups then move to the Troubleshoot section for resolving the issue.

8. You can now set up your Google account and enjoy Chrome OS along with Windows 10. In case, WiFi or any other hardware device is not working on Chrome OS then move to the Troubleshoot section to find a solution.

Note: Before logging into your Google account, keep in mind, you are officially not allowed to run Chrome OS with Play Store support on non-certified machines. In some ways or the other, you might be violating Google’s terms and conditions. So, I would recommend you to sign in with a secondary Google account so that your primary account remains safe.

Uninstall Chrome OS From Windows 10

If you want to uninstall Chrome OS from Windows 10 then the steps are quite easy. Just boot into Windows 10 and open Disk Management. After that, right-click on the Chrome OS partition and format it. Next, open Grub2Win and remove the Chrome OS entry and save changes. You are done.


If you are getting a “Not enough space to create image file” error then I would recommend you to follow my partition rules in “Create Partition” section. It has seemingly worked for many users.

For users who are getting “failed-to-get-canonical-path-of-cow” error, I would recommend you to not worry and move to the next step. Many users have reported that despite the error Chrome OS dual boots with Windows 10 successfully.

And if you are getting “read-only file system” error then you have most probably put the “Chrome OS” folder in the USB drive. You should store the folder in your computer’s drive. You should also disable the “Fast Startup” option in Windows 10 from Control Panel and check if you are still getting this error.

In case, you are still getting all kinds of errors then just create one more unallocated drive in Disk Management (14GB or more) and install Linux Mint on this partition. After the installation, boot into Linux Mint without the USB drive and locate the “Chrome OS” folder, and execute the script from there. I am pretty sure, you won’t face any error this time.

Apart from that, many users have complained that after the initial few bootups, the Grub2Win interface does not show up and the computer directly boots into Windows 10. It happens because Windows is overriding other EFI interfaces.

For a quick solution, you can press the boot key (F7, F8, F9, etc.) during the startup, and from there, you can select the Grub2Win EFI interface. After that, you will be presented with a multi-boot option. I know it’s a hassle to press the boot key every time during startup, but it’s a quick solution and one that works.

If you are having issues with WiFi, Bluetooth, touchscreen display, etc. then you can try adding support for your specific hardware device from the Crosh terminal. Just open Chrome on Chrome OS and press Ctrl + Alt + T to open the Crosh terminal. After that, enter shell and hit enter. Now, run sudo edit-grub-config. Here you can add support for your hardware device. You can find the complete list of commands from here.

For example, if you have an RT3290/RT3298LE Bluetooth device then you can add “options=rtbth” (with quotes) at the end of “cros_debug” and before loop.max…. Now, press Ctrl + X and press “Y”. Next, hit enter to save the file. Finally, restart your computer, and this time Bluetooth should work fine.

Similarly, if you want to fix WiFi then first you need to find out the manufacturer of the wireless card. If it’s Broadcom then add to the same line like this: “options=rtbth,broadcom_wl”. This will fix both Bluetooth and WiFi issues. You can remove rtbth if Bluetooth is already working for you. Similarly, if it’s Realtek then add “options=rtbth,rtl8188eu” or “options=rtbth,rtl8821ce”. Basically, you can add support for hardware devices in this fashion: “options=option1,option2,…” (without spaces) to activate them.

Enjoy Chrome OS and Windows 10 on a Single Machine

So that is how you can install Chrome OS on a Windows partition and boot both the operating systems on a single machine. While the steps are quite lengthy and complex, if you have dealt with Linux systems before then you can easily dual boot Windows 10 and Chrome OS. Anyway, that is all from us. If you are facing any issues then do comment down below and let us know. We will definitely try to help you out.

  14. Thanks beebom. Everything gone right with every steps being followed and now I am happy to be using Chrome OS on my laptop right now. Os is running very smoothly. Thnks so much again.

  15. I have errors during the installation:
    Not enough space to create image file
    Copy the above grub menu entry in grub customizer
    sudo: grub-customizer: command not found
    (I am use the live version of elementary os)

  16. awesome I just recommend an additional step to convert the .sh files from windows to Unix format this resulted in lots of troubleshooting to identify root cause of shell script errors bottom line thank you! i’m triple-booting!

    1. I have errors during the installation:
      Not enough space to create image file
      Copy the above grub menu entry in grub customizer
      sudo: grub-customizer: command not found
      (I am using the live version of elementary os)

      1. just right click on the unallocated partition you had created before and select create a new partition and select ntfs and enable fille and folder compression and then boot linux mint and then select the unallocated partition this time there will be no error so chrome os will be installed on the unallocated partition and files will be stored an the new partition which was created before

  17. I successfully installed chrome os but whenever I open play store it is showing me something went wrong error code 7 I tried logging in with some other account but it is still showing me the same error code

  18. Great tutorial worked perfectly with very few errors but was fixed with the help of Comment section.

    Any ideas to fix this problem?

  31. To those people who have AMD devices I’ve installed the Chrome OS on my Acer Nitro 5 with Ryzen 5 3550H and it works fine. I’ve downloaded the ZORK file instead based on in instructions.

    One step I had trouble though was on the partition part once I booted the device on Linux because I kept getting the name of the partition as ‘nvmeOnp4’ not ‘dev/sd4’ or something like that and installing Chrome OS didn’t work. What I did was click the drop down button on the right side and select the drive D where I made the partition and it worked.

    I also had to turn off Fast Boot on my Windows power plan settings so that the GRUB2WIN startup will show up.

    One thing I noticed though is that I couldn’t seem to download the latest version of the OS which was 89 from the version 87 I have installed. I still couldn’t figure out how.

  32. Can you please give me a Google Drive link for downloading? I am facing some problems while downloading it.

  33. As I understood now, the greate script of Kedar Nimbalkar works good IF:
    The partition for installation must be sdX (sda, sdb, sdc and so on) between 1-4 (for ex: sda1, sda2 . . .). if you partition name is something like “nvme0n1p7”, this script gives you different errors.
    But even in such case there’s a universal way out: You must install Chrome OS on external usb-HDD, where you may create a partition with name sda1(for ex.) of the same size wich is on your internal hard drive. After finnishing of the script you can get “chromos.img” file with immage of your Chrome OS and “chromos.img.grub.txt” with strings for Grub4win. Now copy “chromos.img” to your internal hard drive patition and while settin up Grub4win you must edit Chrome OS loadin item. The string something like “img_part=/dev/sda1” could look like “img_part=/dev/nvme0n1p7”. After restarting your PC Chome OS will be installed on your new partition and will work great.

    1. And some more details: There’s only one correct name for bin-file in script – “rammus_recovery.bin”. Rename your bin-file so.
      And one more thing. The partition which you’re going to use for installation must be unmounted.

    2. When i was installing the OS my partition name was nvme0n1p8 and the greate script of Kedar Nimbalkar worked like a charm. So i have to disagree with you.

      1. the latest update to Kedar Nimbalkar’s script added support for nvme0n1 devices, so this was a great workaround until it was made obsolete

  34. The Brunch official website is down. It is saying “Brunch website is under maintenance. Please check again later.”(Last updated on 3rd Jan). Also, when I am trying to download Brunch from GitHub, the file is downloading a little and then it is saying “Failed-Forbidden”. Any ideas to solve this problem??

  36. To resolve “Not enough space to create image file” isuue, I put space before and after partition… Worked for me. After several attempts, finally figured trying this, and it worked…

    1. Hello Rodney,
      Will you please share more details on this, I am facing same issue & not able to resolve the same.

      1. I was facing the same issue “Not Enough space to create image file”, I was using 16GB Ubuntu live Usb to install ChromeOS, I noticed that when i created the bootable usb using Rufus it gave me less than 3GB to store the file on USB. So i completely installed the Ubuntu on my laptop and tried to install again and it worked..

  37. Hey, there is a new recovery for ryzen CPUS called Zork, I don´t know if it will work with older versions of ryzen.

    1. I don’t know how much older you are talking about but it work perfectly on Ryzen 3rd gen. i am using Ryzen 3550H.

  38. Even after following the exact same steps and partition way as yours , i get the error “failed-to-get-canonical-path-of-cow” . What can i do ?

    1. In this case you have to install Linux Mint as a Dual boot on the computer itself (for example: Windows 10 with Linux Mint), not as a bootable stick. Why? The stick is only mounted as readable only

    2. In this case you have to install Linux Mint as a Dual boot on the computer itself (for example: Windows 10 with Linux Mint), not as a bootable stick. And procede as instructed above

    3. I got this error. However used the live version of elementary OS, and it worked installed the chromeos. Tried a lot of other Linux versions first without success

      1. I used the live version of elementary os too, but I have errors during the installation:
        Not enough space to create image file
        Copy the above grub menu entry in grub customizer
        sudo: grub-customizer: command not found

    4. I was getting the same error but on Live version of Ubuntu, so i installed the Ubuntu on my laptop and it worked.

  39. after first reboot and chosen chrome os to boot from
    there is a error message
    ERROR : no suitable video mode found.
    booting in blind mode
    *nb: i have 2 hard desk in my laptop ssd and hdd
    windows on ssd
    and 100gb , 60gb i created them on hdd

  40. at worked. Will research on having a few more issues on the installation. At times it just gets stuck at installing Windows when it gets to “Getting files for installation” and sometimes when redoing the complete setup again, I get “No bootable deivce”.

    1. Check if you are not getting any other error in terminal, if not and your installation is complete just ignore it.

  41. How come You have a 6 Files in a folder CHROME OS after You extracted Brunch files.
    I extracted Brunch files and… I only have 1 file ( brunch_r81_k4.19_stable_20200510 ), WHY?

    1. That’s a folder. You take those files and cut and paste them into chrome os folder. Boom now 6 items. You’re welcome

  42. Help. In terminal, I put ntfs but it’s always in logical drive, I can’t switch to primary partition. And it all goes well till I want to boot Chrome OS. It starts, and then restarts and boot windows again. BTW on Grub I don’t see windows boot, just Chrome OS. Can you help me?

  43. Great guide. Thanks. I was successful until the last step. When I try to install Grub2Win, I receive the error message “The minimum allowed display size is 1024 x 768. The current display setting is 1280 x 720”. This is incorrect as my current display resolution is 1920 x 1080

    How do I bypass this error?

    1. Change the resolution of your computer display to 1024 x 768 in settings and install it. After that, change it back to normal.

    2. Try to set scaling in display settings to 100%. After installation you can set it to recommended again.

  44. i cannot install grub2win in my window 10 seems like the app is broken
    do we have an alternative beside grub2win?

  45. Hi thanks for the guide!
    I have successfully installed chrome os on my hp laptop but there is no sound coming out from the speaker, however the earphone does work when connected, does anyone have a clue?

    1. I had the same problem when installing ChromeOS from within linux mint

      What I done was made the file read write and it fixed my problem

      On a HP stream machine

  46. I did everything and after I click on Chrome OS in the Grub2Win boot menu I get the message: “GNU Grub is now loading Chrome OS”, then the computer reboots directly into Windows, what can I do?

  47. Very good tutorial. It’s working very well.
    I use a lenovo w540 but when i am in chromeos, the compter is overheating.

    I installed rammus version 83 and now i can see that version 85 is available. When i go to about chromeos and i check for a new version, i receive a message saying that my chromeos is up to date.

    How can i update to version 85 ?

    Thanks for your answer

  48. Thanks for your kind direction. I success dual boot with chrome and win10 in my surface 3.
    At the booting with Grub2, can I select boot menu(0 chrome, 1 window….) by using touch screen without keyboard?
    Without keyboard, I can move between each boot menu by volume +, – button, But I cannot
    select it (Enter or click).

    1. Soham, legacy mode is an old mode for booting, so u just cant install chrome os on legacy(and believe me i’ve tried)
      anyway, if u havent installed linux mint then no your windows will not be destroyed.

  49. I have installed samus recovery do I need to rename recovery file to samus_recovery instead of rammus_recovery.

    1. No man it will not work if you rename it any thing other than rammus_recovery.bin, because Kedar Nimbalkar script don’t recognize any other name. I tried using zork.recovery.bin and it gave me error rammus_recovery.bin not found. So i rename it rammus_recovery.bin and it worked perfectly.

  50. The error, “Not enough space to create image file” occurs if the partition size in which you are installing the Chrome OS is greater than the size of the partition from which you are running the installer.

  51. Hi Arjun,
    Thank you for your detailed explanation. I managed to make it work despite the /cow error after installing ChromeOS. Followed your advice to ignore it and copy the menuentry details. Worked fine. The only think not working at all is the microphone. Tried with different apps and websites. Do you know how to fix this? And also the clock of windows is not working properly as well.
    The machine is a Dell E7250 Intel i5-5300 with Realtek mic and audio. Thank you

    1. Jorge, did you end up getting your mic working? The only thing not working for me is the mic too.
      Cheers Shaun

  52. Hi, if I am currently using one OS, how do I switch between it and Windows 10? Do I have to restart the computer?
    Thank you

      1. I’m getting following error read-only file system
        sh: 0: Can’t open

  53. The PC I have is only having 160 GB storage so how can I make a partition. Moreover, 32 Gigs is already less because of a EFI System Partition, as I recently installed windows 10 on it. If I create a partition of 100 GB for chrome os and only leave a little for windows 10 (as I will use chrome os majorly and will use windows 10 only for certain functionalities) will it work?

  54. Great tutorial and I’ve got to successfully install and boot chrome os on my laptop and have been able to use it flawless for first and last time. Later when I run windows and tried again to boot into Chrome OS from win2Grub boot menu, it’s throwing an error “the disk contains unclean file system” and a screen splashes saying system repairing itself on chrome os and then directly boots into windows login screen. Any idea on this?

  55. Hello! Thanks for the article. After a few errors I managed to install chrome and it is running beautifully!

    I’d like to uninstall windows now and keep chrome OS. Is there a way of doing that or would I have to reinstall chrome OS using a different process to overwrite the windows partition?

  56. For all have an error with grub. The only way to fix that is installing the linux to your hard drive. And then install chrome OS. For me. It works perfectly

  57. u need to install windows 10 and then dual boot chrome os in linux mint as said or just create a linux usb installer and then login in to chrome os and install linux mint . done

  58. my specs are intel i3-3240t
    8gb ram ddr3
    500 gb hdd
    i made a 53 gb partion for chrome os
    used rammus recovery
    plz help

  59. plz help when i start chrome os after configuring grub2win i encounter this product is covered by one or more patents and i some how open grub 2 win with boot and options and select chrome os but after sometime when it reaches root a in that black window it says root a was not cleanly unmounted plz help me .just waiting for reply

  60. This was a great video and very easy to use. Thank you. Like a couple of other users, I have followed the instructions 100% completely utilizing the “rammus” image of Chrome OS and am getting a black screen when attempting to boot Chrome OS. My system is as follows:

    Lenovo Yoga C740-15IML
    Intel Core i5-10210U CPU @ 1.6GHz
    12GB RAM
    256GB NVME SSD (32GB Partitioned as NTFS for Chrome OS)

    1. I discovered the fix for my own issue. In the GRUB editor in Mint, I had to add “rmmod tpm” to the top line of my Chrome OS loader config. This disables Intel’s “Trusted Computing” feature within their CPUs.

  61. I have installed it successfully and it is working fine. Will I get Chrome OS updates or am I stuck with the installed version? Please confirm

  62. I completed all the steps and setup the dual boot option. But when I try to boot chrome os some setup happened in black screen the it ended with last line as ” chromeos was not found on any device, falling back to shell.. ” please help.

  63. I experiences with the error: “failed-to-get-canonical-path-of-cow”
    But I just ignore the error and continue with other steps and finally I can run dual OS.
    Even I can use Chrome OS normally, but it’s still an issue. It is about the clock. The system clock was change when I back to windows, and it only change the time, date and minute were normal. It’s seen like the issue occured everytime I boot to Chrome OS and back to Windows. anyone can help?

  64. I created a partition of 64 gb, it’s shows not enough memory to create img file in Linux terminal

    1. Just got through the install step again and overwrite the partition you chose last time

  65. Followed your guide and everything worked flawlessly on my dell XPS!
    Chrome os is working beautifully, but I do seem to be having some thermal issues where the fans aren’t turning on until the device gets hot, and the battety doesn’t as well as it I was hoping

  66. After entering the command “sudo sh” it shows : read-only file system
    Give some solution.

    1. that was because the [chrome os] folder is inside your linux usb installer. move it into another usb drive and plug it together. i was trying this and its work.

  67. What should I do if I got both SSD(With Windows 10 installed) and HDD(Where I want to install Chrome OS)?

  68. Your tutorial did the magic and now I have the working chrome os in my pc, but how do I run root applications is it possible to use apps like l speed and greenify?

    1. Use which is available on playstore, connect to a dns server. And then open the site. It will work then.

  69. Unable to download the Chrome OS recovery image as the link given above has stopped working…. need help!!!

  70. So, I have completed the dual boot for chrome os with Windows 10, but how can we access windows 10 files on chrome os

    1. Simply speaking you can not. As Chrome OS runs from within a chromeos.img file (you may have noticed it in the ntfs partition in which you have installed your chrome OS) it can not access the files outside it.

  71. I get the error that the where my Chrome OS folder that I created on a Windows drive is read-only while in Linux Mint making it fail when trying to run the “sudo sh”

  72. Hey, the process worked seamlessly. But after two days my computer says harddrive not detected. This never happened when I had installed linux. Please help. Laptop is a Dell Inspiron 3000 series with an i3

    OUTPUT_FILE: /boot/grub/grub.cfg frontside warning symbol

    sir please help

      1. I think I have the same problem. But the grub is not real problem. Perhaps the “” was made for “Rammus_recovery.bin”. I installed Samus and stucked at this step. So, I renamed the file “Samus_recovery.bin” into “rammus_recovery.bin”. And it worked!

  74. Sir i am getting problem in installing the chrome os

    I installed it successfully and it works like a charm.

    Just one question!
    how can I have access to my local hard disk drive (windows and my two other partitions) from this Chrome OS ?????

    Thanks in advance

  78. My Chrome OS stared at first time. But when I restarted my computer ,it started win10 directly. I restart my computer an press F12(Acer), but there has no Grub2win EFI. Please help.

  79. I’m using Linux-mint as my primary OS, I’ve tried all your steps and created a grub menu entry using grub-customizer in Linux-mint,but after creating that grub-menu entry my laptop won’t boot at all and after trying a lot i again reinstalled the OS(Linux mint) .I need some help in how can i install Chrome OS(dual booting with Linux-mint),do i need to partition the empty drives in ntfs format or any other format(as mentioned in step-4 of installing Chrome OS)?

  80. Are there other EFI managers that can create a working bootable entry for the chrome partition? Grub2win cannot run on my system due to restrictions in place on Win10.

  81. Is there any way to access windows 10 NTFS partitions in chrome OS..I searched and tried a lot but nothing works

  82. hi everything is fine in one go dual booted successfully on i3 9th gen intel h370 motherboard but can’t find a way to enable wifi ? only LAN is working any fix ?

    1. To fix WiFi, first, you need to find out the manufacturer of the wireless card. Boot into Windows and find the name of the wireless card from Device Manager. It should be from Realtek, Broadcomm or Intel.

      After that, boot into Chrome OS and open Chrome and then press Ctrl + Alt + T to open the Crosh terminal. After that, enter “shell” (without quotes) and hit enter. Now, enter “sudo edit-grub-config”.

      If it’s Broadcom then add “options=broadcom_wl” (without quotes) at the end of “cros_debug”. Now, press Ctrl + X and press “Y”. Finally, hit enter to save the file. Now, restart your computer, and this time WiFi should work fine.

      Similarly, if it’s Realtek then add “options=rtl8188eu” or “options=rtl8821ce” depending on the wireless card version.

      If the native Intel wireless card is not working then add “options=iwlwifi_backport”

  83. Hi, I installed Chrome OS and did setup in Grub2win by following steps. After rebooting I could see both win10 and Chrome OS but Chrome OS is not loading. What could be the error? After installing Chrome OS, I got this directory:
    search –no–floppy –set=root –file $img_path
    loopback loop $img_path
    linux (loop,gpt7)/kernel boot=local noresume noswap loglevel=7 disablevm
    x=off \
    cros_secure cros_debug loop.max_part=16 img_part=$img_part img_p
    initrd (loop,gpt7)/initramfs.img
    Is this directory is correct? Did I miss something? Do I have to make any changes by removing spaces and blank lines? Please help.

    1. On the Grub2Win interface, scroll down and you might find Boot from Chrome OS image. Open it.

  84. I solved the /cow problem. It seems that when booting from the USB drive, Linux mounts it as a cdrom which is read only. I ended up installing Linux to the 60 gig partition since I saw no other use for it. Then booted from Linux on the hard drive instead of the flash drive and everything worked after that. Then I had triple boot system with windows, Linux, and chrome. I guess I could delete the Linux partition but think I will keep it. If you want details let me know.

    1. yes. I managed to install it using WSL 1. with WSL 2 should do the same, there’s an tutorial in that describe how to use WSL

      Install ChromeOS on a USB flash drive / SD card
      Download the ChromeOS recovery image and extract it.
      Download the Brunch release corresponding to the ChromeOS recovery version you have downloaded (from the GitHub release section).
      Install the Ubuntu WSL from the Microsoft store (refer to online resources).
      Launch Ubuntu WSL and install pv, tar and cgpt packages:
      sudo apt update && sudo apt install pv tar cgpt
      Browse to your Downloads folder using cd:
      cd /mnt/c/Users//Downloads/
      Extract the package:
      sudo tar zxvf brunch_.tar.gz
      Make sure you have at least 14gb of free space available
      Create a ChromeOS image:
      sudo bash -src -dst chromeos.img
      Use “Rufus” ( to write the chromeos.img to the USB flash drive / SD card.
      Reboot your computer and boot from the USB flash drive / SD card (refer to your computer manufacturer’s online resources).
      (Secure Boot only) A blue screen saying “Verfification failed: (15) Access Denied” will appear upon boot and you will have to enroll the secure boot key by selecting “OK->Enroll key from disk->EFI-SYSTEM->brunch.der->Continue”. Reboot your computer and boot again from the USB flash drive / SD card.
      The GRUB menu should appear, select ChromeOS and after a few minutes (the Brunch framework is building itself on the first boot), you should be greeted by ChromeOS startup screen. At this stage, your USB flash drive / SD card is incorrectly recognized as 14GB regardless of its actual capacity. To fix this:
      At the ChromeOS startup screen, press CTRL+ALT+F2 to go into a shell session.
      Login as root
      Execute the below command:
      sudo resize-data
      Reboot your computer when requested and boot again from USB flash drive / SD card. You can now start using ChromeOS.

  85. After booting linux mint and connecting to the internet, I cannot find Chrome OS folder which was created on the flash drive.
    It is saying Unable to mount location( can’t mount file ).
    Could you help me with this issue.

  86. Does rammus support I3 6th gen processor? If I have to use samus, do I have to make any required changes in the scripts like and others? Please guide. Thanks in advance!

  87. Keeping keeping “/cow” error, I doubled the size of the partitions and the error continues. Any tips

    1. Are you getting this error after installing Chrome OS or immediately after executing the script? If it’s former then there is nothing to worry, just copy the menuentry section and continue.

  89. My laptop is on Legacy BIOS. I want to change it to UEFI, but no option of UEFI firmware update is found in recovery help me to change it without any loss of my data.

    1. You can use AOMEI Free edition partition assistant to make UEFI

      3. So, Open AOMEI Partition Assistant select your drive name and right click select Convert to GPT click the tick to complete the operation Your device will restart and go to AOMEI PE Environment. Just wait after you’ll be redirected to Windows login
      If not, Go to BIOS Screen go to boot settings. Tap Legacy Support or UEFI something change it to UEFI or disable legacy boot

  90. Great Article, and truly reflects efforts in compilation and presentation. One aspect I think no one is discussing here and that is, how to go back to pure win10. Will simply wiping out 100Gb partition and editing bcd will bring my notebook back to pure win10?
    Enlight and educate us on reverse process too

    1. Yes, just format the Chrome OS drive from Windows Disk Management, and you are done. You can also edit the BCD to remove it from the boot menu. Or remove Chrome OS entry if you are using Win2Grub.

  91. While booting Chrome OS from hdd I’m facing problem

    “error: no such partition
    error: you need to load kernel first
    Press any key to continue… “

  92. Hi,
    i am getting the following error while i type in terminal windows sudo sh
    ERROR comes : Read-only file system
    sh: 0: can’t open

    please help

    1. Even I experienced the same yesterday. Please check for file system errors. Type boot in the start / search and launch boot-repair window. There you can fix file system errors. During the process your partitions will unmount and remount again. After doing this process I got all permissions like read and write back and I successfully ran hope it helps.

      1. If you are still facing the problem then move the Chrome OS folder to a separate USB drive (not the Linux Mint USB) or external hard disk. After that, connect the USB drive and run the script. You won’t face “read-only” error.

    2. I tried the fix posted by Lakshminarayana and it did not work for me after several attempts. I just simply made a folder in the Linux window and copied over the files (6 files) from the Chrome OS folder on the USB to the new folder and ran it from there. I believe Arjun Sha’s method may work too, but I didn’t try it.

  93. Hi, Since I don’t have 16 GB flash drive, I loaded linux mint using bootable DVD. I successfully created partition named sda8 by following your steps. I’m getting error “failed to get cononical path of cow” when I’m trying to install chrome OS in to sda8. please help.

  94. Thanks for posting this comprehensive guide. Before I embark upon the many processes listed I would like to ask a question. I have a desktop machine with 4 hot-swap disc drive bays. I have several SSDs, each configured to run as a single stand alone system [Windows, Ubuntu, UnUbuntu, Cloudready etc.] without the need for dual booting or having to choose from a grub menu. For a number of reasons I find this makes for an easier life without any of the OS’s being aware of the others. Would it be possible to outline the necessary steps to run Ubuntu [or if necessary Cinnamon] to create a separate image of ChromeOS on it’s own SSD. In all cases any SSD / OS can then be selected from one of the 4 bays using the ‘boot menu’ key [F8 on my Tower PC] or where more than one SSD is occupying the hot swap bays the load process will go ahead defaulting to the first SSD it finds [that is available in the lowest numbered slot connected to the mother board] and that system will load in isolation. I hope I have explained this clearly – if not please ask for clarification. Thanks, Phil

      1. I did with Multi-Install but all of my data on my 2TB drive is gone. I created a separate 100GB partition for it.
        How can I recover my data please help

    1. You need to save the file with line ending:Unix/Linux. This can be done by right clicking and editing the. Save as and you’ll see the option

  97. After entering sda8 in terminal and it asked me for comformation. I typed “yes” and gave enter. I’m getting the error “failed-to-get-canonical-path-of-cow”. I followed your steps in creating partition. Still I’m getting this error again and again. Please help.

  98. In this configuration will the laptop take windows 10 and Chrome OS updates without issue or are you stuck with the installed versions?

  99. Touchpad not working, its clicking but cursor would not move and disappear after click.

  100. After entering into mint os keyboard is not working… If enter through compaitable mode keyboard is working but touch pad is not working. So I’m unable to install chrome os .. Really in need of your help

  101. I wish there were a magical way to put Windows 10 on my awesome Chromebook so I could have Photoshop finally. Chrome OS’ biggest curse.

  102. have it installed on my mi notebook air 12.5 dual boot with windows 10 with no issues whatsoever. awesome.

        1. Open Chrome and press Ctrl + Alt + T to open the Crosh terminal. After that, enter “shell” (without quotes) and hit enter. Now, enter “sudo edit-grub-config” Next, add “options=mount_internal_drives” (without quotes) at the end of “cros_debug” and press Ctrl + X. Now, press “Y” and then hit enter to save the file. Finally, restart your computer, and this time Windows partitions will show up.

          Keep in mind, Android will scan your partitions initially so it might take hours depending on your data.

  103. I’m sure this is useful and easy but want to know if there is any update regarding AMD? I’m using Ryzen5 3rd gen + Vega 8

  104. I am using the xiaomi mi notebook air 12.5 with intel core m3 processor, will it be more compatible by downloading the chrome os version that is built for a laptop with the same processor like the samsung v2 (nautilus instead of rammus).

  105. I have done partition exactly like u said but getting not enough space to install image error and when i type sudo sh and press enter in first line it says “cannot add PPA: this PPA does not support focal” is this an error ?as i have not seen this error in youtube videos.

    1. I have a solution for this one. You need to download mint version 19.3 not 20.0. Conical changed the package type.
      I however am still getting the grub2 error about not finding the /cow path. Let me know if you get past that part.

      1. Are you getting this error after installing the Chrome OS image (writing partition) or immediately after running the SH script? If it’s the former then no need to worry. Copy the menuentry section and continue with the steps.

  106. Looking at all the recovery images for chrome there are sooooo many choices. I know that your site says to use the rammus version, but why not a different one? How can you tell? I am running an Intel core i7, 7th gen.

  107. Hi,
    Already followed all of your instruction, but still stuck at the Chrome logo while booting up. Is there any solution for this? I tried rebooting several times but the problem persists.

      1. Hello, I have the same problem. My computer is stuck at Chrome OS boot screen, I have found the TMP option in the BIOS and turned it off but still failed, please help me.

          1. Thanks for answering. I look forward to your assistance.
            My PC configuration is: intel Xeon e3 1270 socket 1155 CPU
            RAM 8G, SSD 120G. I downloaded and installed Samus

      1. I tried this many times using windows 7 and still bootloop. Is it because I didn’t have UEFI support or what? My laptop is Acer Aspire 4739 (Intel Core i3 – M370@2.4 GHz), RAM 4 GB, MBR HDD 300GB

  108. A great article !
    Please can u guide me which CHROME OS version should I download for my AMD A-8 7410 APU. Thanks in advance.

  109. I am having a problem when I am trying to execute the .sh file in linux it says: Read-only file system
    sh: 0: Can’t open
    Can you please help me out with this , I m eager to install this thing.

    1. Move the Chrome OS folder to a separate USB drive (not the Linux Mint USB) or external hard disk. After that, connect the USB drive and run the script. You won’t face “read-only” error.

    2. Disable the fast startup option in power menu in win 10. It will solve the problem.

      1. Thanks, Akshat! That worked for me. I didn’t know that Win 10 didn’t shut completely down after I chose “Shut Down.” That, of course, locks the file system. All of the other step-by-steps were very well written, but the locked file system had me frustrated until I read your entry. It takes a village …

    1. This is a non-issue. Just copy the menuentry section and move to the Dual boot section. You seem to have installed Chrome OS successfully.

      1. Didn’t find the menuentry section. I faced the similar problem of error while loading grub list.

  110. I have a question… supposedly all works fine and i successfully run both chrome os and windows on my machine….and then i start using chrome os for all the day to day tasks like surfing the web and watching netflix etc over windows…. wouldn’t that result in way better battery life in my laptop? As chrome os is fairly light weight (it is a browser afterall) compared to windows….no one seems to talk about this in any YouTube videos.

      1. Hey beebom ,
        My laptop is on legacy BIOS and not showing any option of UEFI firmware in recovery settings ,so help me to convert legacy to UEFI with any data loss.

        1. I think you can’t do that, your laptop must be old because from last, I guess 4-5 years every manufacture includes both option.
          And basically UEFI is a upgrade to LEGACY.
          If your BIOS doesn’t have UEFI than you can’t do that because it is a fundamental things that you can’t do anything about.

          1. It’s really sucks, you can install cloudready chromeOS on a LEGACY BIOS but not dual boot with Brunch ChromeOS

  111. hey you’ve forgot to mention how to mount internal drives in order to access files, folder from all the other partitions on your hard disk. You have to write options=mount_internal_drives in grub command line in grub2win. You can also enable updates by including enable_updates. yOu can find these in Framework Options on the brunch page

  112. I already did it several months ago after watching Kedar’s YouTube video. It’s more easy and the total credit goes to Kedar only.
    Search Kedar Nimbalkar on YouTube, and give it a try.

    1. This time, merge the two partitions and then follow the same procedure. You will only have one unallocated parition.

  114. When i try to run the command for, it shows error “Read Only file system”

    Please Help

    1. In that case, move the Chrome OS folder to a separate USB drive (not the Linux Mint USB) or external hard disk. After that, connect the USB drive and run the script. You won’t face “read-only” error.

  115. Hey Beebom,
    I think there is a problem with the file.
    I am getting this error after executing sudo sh in terminal :-
    “ Read-only file system
    sh: 0: Can’t open”
    I didn’t encountered this problem when I was installing ChromeOS on whole system.
    Things I tried after encountering the issue:-
    1- I flashed my USB again with Rufus and copied that “ChromeOS foler”. Same issue.
    2- I tried different laptop. Same Issue.
    3- I kept everything same in USB, just changed the with (file from
    “ ” this article to cross validate my files), it worked like a
    So probably something is wrong with the file
    Hope to get it fixed soon.


    1. You don’t need to copy the Chrome OS folder to the USB drive. You have to keep it on any of the Windows partition and from there execute the multi_install command. The installation process is slightly different from the earlier method.

      1. If you are still facing the issue then try this fix. Move the Chrome OS folder to a separate USB drive (not the Linux Mint USB) or external hard disk. After that, connect the USB drive and run the script. You won’t face “read-only” error this time.

  116. Is using cinnamon image necessary, i have ubuntu installed in one of my partition, can i use it instead of live cinnamon usb?
