Well, bios_grub and raid aren't flags. They're partition types.
The gpt layout doesn't have as much spare room in it as the older mbr.
Creating a small bios_grub partition gives some space for grub to
install parts of itself.
You need to create a small (recommend 1MB) partition for bios_grub, then
the rest of the drive can be a linux raid partition.
