Problem: can't get Gigabyte GA-Z270M-D3H with latest BIOS (3/9/2019) to even recognize a Rufus-made bootable thumb drive as a valid boot option.
Background: the thumb drive in the retail Windows 10 box has something wrong with it; although it is recognized as a UEFI bootable device by the Gigabyte MB, I cannot boot from it. Nothing happens when I choose that UEFI partition from the boot menu. The Gigabyte splash screen just sits there.
So I downloaded the Media Creation Tool and created a bootable thumb drive. It didn't work either. The system just sits at the Gigabyte splash screen when the choice is made from the boot menu.
So I downloaded Rufus and an ISO from Microsoft and made a bootable thumb drive. But I cannot find a combination of BIOS settings that result in it being recognized as a valid boot option. It doesn't even show up. I've tried turning CSM off and on. Tried changing storage options from UEFI to Legacy. (I don't see a "both" option as this ASUS user on the Toms Hardware site reports on his MB: ASUS BIOS refuses to boot from UEFI flash drive w/ rufus).
