Came up this Menu:

Please Select Boot Device:

AHCI PO: ST1000 DM013

AHCI PS: HL-DT-ST DVDRAM GH24NS

USB: USB3.0 Flash Drive PMAP

UEFI: USB3.0 Flash Drive PMAP


The first 3 options are quite straight forward, I think, HDD , DVD. and the USB Flash drive;

but, the last option, UEFI USB 3.0 what is this? Isn't it the same as the third option?

It is a Asrock M'board.

Cheers.

A simple way to explain ( kind of) is (Example) windows 10 will boot from either, as its UEFI capable, But I have a partition program that if I try to boot from UEFI, it wont work, its an older program that doesn't support UEFI, so I have to change the BIOS back to Legacy.

Think along the lines of the USB is the old Legacy Where as UEFI is the Newer option.
