You seem to have installed Windows without UEFI. You'll have to reinstall Windows. Make a fresh windows USB drive using Rufus. Make sure that you select GUID (GPT) as the partition scheme. Otherwise, you'll end up with Windows in legacy mode again. After that, disabled legacy bios and boot into the USB via UEFI.

it is still a workaround instead of a proper clean install from scratch.
He's even gone to the trouble of making an ISO with drivers included.
