I was about to say that at least in Ubuntu, linux automatically loads
via EFI and then falls back to native grub kernel loading if that
does not work (and it's not on secure boot). Which IMO is the right
thing to do.
Also the other point is that this actually breaks stuff if you install
both MBR and EFI bootloaders. Which is something you actually should
be doing because you still want to be able to boot even if user switches
their BIOS from UEFI to BIOS or vice versa or other shenanigans.
