Well, as for the thumb drive: formatted in FAT32
I placed all the (unzipped) BIOS files (F3 to F7) on mentioned drive, put it into the computer and flashed it using the BIOS provided flash utility.
Actually I did this a number of times, trying several BIOS releases. Its a strange thing; initially, the mobo came with F5 OOTB; once I realised macOS wouldn't boot with F6 I reverted to F3 (running really well on a second machine). Out of curiosity I later upgraded to F5 again without success. I therefore ultimately decided to go with F3 .
As it seems, some forum members even could upgrade to F7 without issues. No idea what might cause this weird behaviour
I've currenly tried F3, F4, F5, F6 and F7, and it keeps only recognizing "Windows Boot Loader" as an option. I've seen some posts on Gigabyte forums about defective BIOS chips, maybe that's the case. Hopefully I can get this issue figured out. I really have no other way of getting into my PC.
