I started with MBR, and then I converted it to GPT using gdisk which was
a bad idea. It may have worked if I started with a GPT formatted disk,
but I got a missing-bios flag error message before the conversion.
Using bad advice from the internet, I added this flag to a partition
using gparted and proceeded to lose all the data in that partitions. Oops.

Maybe that's the source of the "unrecognized signature" that I was
seeing. I agree, there's nothing to suggest that grub2 can handle
DragonFly out of the box. To be fair, FreeBSD people were getting the

I don't know, I'm sorry. My grub knowledge is very limited.
