Is there a way to make this configuration work? (I've used gdisk to
convert DOS partition tables to GPT, so far.)
Yes... make a BIOS Boot Partition!
Such a partition couldn't hurt with DOS tables, too (I think there isn't
a way to mark the partition table type as such in msdos tables, though?
So maybe it can't be done / done easily.)
Basically, on msdos partitions, there's usually a post-MBR "gap" where
there are no partitions and a part of GRUB is put there. It can't be
put in a filesystem because filesystems can shift their files around,
and it's loaded by the <512 byte MBR, which can't be very smart. GPT
tends to fill up all the space you'd have a post-MBR gap in, so you have
to do the more-explicit-and-reasonable approach of making a partition
for the GRUB data (in GRUB2 we call it core.img).
