How to create a Windows 8 / 8.1 / 10 bootable USB drive installation media

If your computer doesn’t have an optical (DVD) drive, how do you install Windows?

  • Go to another computer with a DVD drive.
  • Use ImgBurn to create an .ISO file from your Windows installation DVD. (you can use an alternative application if you want)
  • Don’t bother with Windows 7 USB/DVD download tool. Use Rufus. It’s perfect. You give it the .ISO file and a flash drive (your USB drive) and it will turn your flash drive into a Windows installation media.
  • Boot from the flash drive and install Windows.
