GRUB EFI blues - Debian 9/FAI 5.3.6

[tt-fai at kky.ttu.ee]

I can second to that. I installed a SuperMicro X10SLM-F based server last
month and did not find any option in the BIOS to PXE-boot FAI into UEFI
mode. Ended up using disklabel:gpt-bios and GRUB_PC. I did not try to boot
off an USB stick, so it is worth investigating if an option exists for
booting that in UEFI mode.

 

>From my experiments I was left with the impression that it is not easy (or
even possible) to "cross-install" UEFI-boot-capable disk if the system was
booted into legacy (BIOS) mode. If someone has found a way to do it, I would
also appreciate suggestions.

 

Regards,

Toomas

I think the first issue is FAI is setting the GRUB_PC class instead of the
GRUB_EFI class and I'm not sure why.

I am pretty sure this depends on how the installation was started. That
means you will have to boot your FAI installation using UEFI as well. This
can be a bit tricky if you want to install from network - I also tried
setting up PXE with UEFI some time ago and failed.
