  • UEFI is successor to EFI as Akito correctly noted; GPT is "related" in a sense that MSFT chose to couple UEFI/GPT, BIOS/MBR for some reason (I can understand a part of it but don't know for sure) so many firmware manufacturers will assume that's the only combos they have to test.

  • Regarding GRUB, what exactly do you see instead of its menu? "console" means textmode console, not a graphical menu; looks like this doesn't work with UEFI GOP correctly in your case, maybe switching to e.g. "gfxboot" with some GRUB_GFXMODE='800x600' nearby and a grub-mkconfig as GRUB2 expects would help. If CentOS isn't a given, you might also try e.g. Debian, openSUSE or, well, ALT (I've implemented UEFI support there :). Commented Mar 28, 2017 at 8:10
  • For general (U)EFI introduction, and a pretty good and readable one, I'd warmly recommend Rod's books on this topic, helped me a lot back then. Commented Mar 28, 2017 at 8:11
  • @MichaelShigorin: CentOS is a given. I have a blank screen except for the wrongly aligned display counting down when my "selection" will be chosen. Commented Mar 29, 2017 at 3:59
  • try switching GRUB to gfxboot then. Commented Mar 30, 2017 at 9:06
