How To Create a Bootable USB For Windows 7, 8 or 10

Last Updated: September 27, 2016

If you have lost your Windows installation disc or the manufacturer of your PC didn’t provide the disc (most don’t provide now), then you still do have an alternative. You can just create a bootable Windows USB drive to install Windows 7, 8 or 10 by plugging in that USB drive. It is actually quite easy and free to do, all you need is a USB drive, Windows ISO image and a dedicated software.

However, the process and tools are actually different for the installation of each version of Windows. The source to get the Windows ISO file is different and the tool required to create a bootable USB drive is also different (or at least the process is). So it is important to know which tools you require and how to create a bootable Windows USB drive for your particular Windows version (7,8 or 10).

In this tutorial, we are going to show you how to get Windows 7, 8 and 10 ISO image (Legal and Free) and create a bootable USB drive out of it to install Windows in any PC (if supported).

Create a Bootable Windows 7 USB Drive

Windows 7 is Microsoft’s most used Windows right now, so its quite obvious that many people still want to know how to create a bootable USB drive of it. Although, Windows 7 is the most used Windows version right now, but Microsoft’s focus is still on Windows 8 and 10 as the represent the future of Windows. So Microsoft doesn’t offer any easy to download or bootable USB creation tool for it.

However, it will still let you download the ISO file separately, but only if you already own Windows 7 product key, not for testing purposes. So getting Windows 7 ISO is not a problem if you are already a owner and just want the ISO for future installations. Otherwise, you will have to install Windows 7 using a DVD disc, which you can borrow from your friend if they have one.

There is no official (legal) way except these two to get a Windows 7 ISO image. You can download the Windows 7 ISO from Microsoft’s software download site by providing a valid product key.

Microsoft also offers a separate tool to create a bootable Windows 7 USB drive, which you can download from CodePlex.
