How to boot from USB using your Windows computers startup system

If the Windows 10 boot method doesn't work, it might be because your PC's BIOS (basic input/output system) doesn't support it. You can still boot from the USB drive, though you will need to tweak the BIOS settings.

Unfortunately, every BIOS screen is configured differently, so you will need to explore the options for yourself.

1. Shut off your computer.

2. Turn it back on and press the key indicated briefly on the startup screen to enter your BIOS Setup. It's usually Escape, F1, F2, F8, F11, or F12. If no such screen appears, your BIOS may be set to "fast boot" mode, so you will need to experiment with different keys at bootup, before the Windows screen appears. For more information, you should consult the documentation that came with your PC .

3. In the boot menu, look for the boot order controls and move the USB drive to the top of the list.

4. Save your settings and restart the computer with the USB key installed.
