Does grub install its bootloader into the MBR, or in a GPT = boot > partition? I am not at all familiar with this new way of booting systems= . I think basically GPT is a replacement for MBR, everything basically works the same way otherwise. GPT has features like redunancy, removes limits of MBR (no primary/logical designation anymore, no 2TB limit, etc). I think it has a somewhat MBR-compatible layout in the first sector so non-GPT-aware things can still partially recognize it.
