When a GPT partition table is present on the system, a small BIOS boot partition with type  (which is different from the EFI System Partition (ESP) which has type  ) will need to be available. 1 MiB will be enough to work but 2-4 MiB is a safer option. This BIOS boot partition will hold the stage 2 of the bootloader. BIOS boot partitions do not need formatted with a filesystem; the grub2-install command will overwrite any pre-existing filesystem with one of its own.
