I repeat : the point is not MBR/MSDOS vs GPT. It is that the GRUB installer handles *specially* one type of partition which exists only in GPT style : "BIOS Boot" aka "bios_grub". Are you talking about the installer code run by grub-install or the bootloader code ? I am not aware that the installer code can handle any partition type other than the above type in the same way.
