Can't mod gigabyte h110m hd2 cf to run with i3 9100f

Used q flash to modded bios but it said “invalid BIOS image”
I have followed this video too: https://youtu.be/HKlA2YMasSg?si=NyboFHUtzFgZ7AMP but at cmd step it said “Error 366: Fail to load driver (PCI access for Windows). Tool needs to run with an administrator priviledge account.”
This way also didn’t work for me too, i can’t boot from rufus usb to get into FreeDOS: Flashing Gigabyte while avoiding "Invalid BIOS image" - #5 by rootuser123
I don’t know what to do now, can someone help me
