--- Comment #48 from Ben Bullard <benbullard79 at cox.net> ---
My understanding is that this is an irrelevant issue. But there is something I
don't understands. In UEFI systems booting takes place from /boot/efi partition
not from mbr or 'disk'. BUT if that is true then why does grub2-install need to
be pointed to /dev/sdx, ie. a 'disk'? Or has this just not been well explained?
Exactly what is grub2-install doing on a UEFI system since it isn't installing
boot loader to MBR? 

In other works what I *think* I understand is that regardless of Calamares
saying boot loader is installed to /dev/sda booting doesn't take place from
/dev/sda or /dev/sdx but from the /boot/efi partition. Isn't this correct?

I do know (don't ask) that if one somehow erases or formats /boot/efi you
aren't going to boot anything. So in that instance whatever is allegedly on
/dev/sda or /dev/sdx doesn't boot anything.
