Use Microsoft’s own Windows USB/DVD download tool to create a bootable drive you can install Windows from. You’ll need a Windows installer ISO file to run this tool. If you don’t have one, you can download Windows 10, 8, or 7 installation media for free — you’ll need a legitimate product key to use them, though.un the tool, select your desired distribution, browse to your downloaded ISO file, and choose the USB drive you want to use. The tool will do the rest. You can use similar tools on Linux. For example, Ubuntu includes a Startup Disk Creator tool for creating bootable Ubuntu USB drives.
