Question

Windows

I need to reinstall Windows from BIOS, but nothing happens.
Probyval from a bootable flash drive:
1) The flash drive is definitely bootable
2) The BIOS is configured correctly
3) PROFIT????
4) Nothing

. Here such shnyaga comes out and does not disappear.
It’s the same with the disk (((
Only it’s longer (

I got a little fired up in the pictures, but I don’t care, the main thing is to find out what’s wrong with the computer.
And by the way, the disk and flash drive have already been used on this computer as bootable!

Answer 1

UEFI Boot is enabled, and the flash drive, obviously without an EFI partition, does not boot.

Answer 2

Change the BIOS setting regarding boot - change the GPT (Legacy) mode to UEFI, or vice versa ..
