Reinstalling Windows 10 which usb?

[kittensnouterspace]

My brother needs to reinstall windows 10 due to some os issues. He wants to start fresh. Which USB version should he choose? UEFI or the standard USB?

Thanks in advance for any help!

either one should work, i usually go with the regular one. worst case scenario, you have to go back to this menu and select the other, so no big deal if it's the wrong one.

I would go with UEFI..

UEFI. Unless you feel your computer is too fast for you and want to slow down its startup performance drastically, and reduce your system security, if you think it is also too high.

Thanks everyone for your input, we went with UEFI.
