On BIOS platforms GRUB has to use a so called embedding zone. On msdos partition tables it's the space between MBR and first partition (called MBR gap), on GPT partition it uses a BIOS Boot Partition (a partition having type 21686148-6449-6e6f-744e656564454649). If you use GRUB on BIOS be sure to supply at least 31 KiB of embedding zone (512KiB or more recommended).
