Public bug reported:
This may be firmware bug.
This commonly happens on Intel S5520HC, HCV and HCT motherboards. It's
dual LGA1366 system, and this happens only in UEFI mode. Legacy works
fine. I suspect BCD region in UEFI is marked read only, so grub and shim
install fails. On this board I have to manually add boot entry and path
to EFI executable.
It's also impossible to completely install Ubuntu on this.
Affects Intel's S5520UR, and WillowBrook systems.
