GRUB2/"does not have any corresponding BIOS drive"

I'm at the stage in the beginner's guide where I install my bootloader and generate a config file.

grub-install /dev/sda
probing devices to guess BIOS drives. This may take a long time.
/dev/mapper/..//dm-0 does not have any corresponding BIOS drive.

I've tried

grub-install --recheck /dev/sda

but to no effect; I just get the same output.

EDIT: It might be worth pointing out the source of my confusion; I'm following this guide and it says to install grub2, but:

grub --version
grub (GNU GRUB 0.97)

Isn't this the legacy version? To install Grub2, do I need to go back and redo all my partitions just to get a 2mb boot partition?

Re: GRUB2/"does not have any corresponding BIOS drive"

For your error: Did you do a

modprobe dm-mod

before the install (see)?

For your question: You are apparently using an old image. The default boot loader was changed to Grub2, but only very recently. It is fairly easy to install Grub2 over Grub,but no big use to install Grub at all now.
You don't have to redo your /boot partition for it at all, but 2mb wont be enough for it usually.
