Download Windows 10

If your PC does not automatically boot to the USB or DVD media, you might have to open a boot menu or change the boot order in your PC's BIOS or UEFI settings. To open a boot menu or change the boot order, you'll typically need to press a key (such as F2, F12, Delete, or Esc) immediately after you turn on your PC. For instructions on accessing the boot menu or changing the boot order for your PC, check the documentation that came with your PC or go to the manufacturer's website. If you do not see the USB or DVD media device listed within the boot options, you may need to reach out to the PC manufacturer for instructions for temporarily disabling Secure Boot in your BIOS settings.

If changing the boot menu or order doesn't work, and your PC immediately boots into the OS you want to replace, it is possible the PC had not fully shut down. To ensure the PC fully shuts down, select the power button on the sign-in screen or on the Start menu and select Shut down.
