/dev/sda8 does not have any corresponding BIOS drive.
However, given that (hd0) is supposed to be /dev/sda (first hard drive, MBR), and /dev/sda8 is supposed to be (hd0,7), this appears to be a bug, as grub-install is attempting to install to a partition (specifically, the root partition), rather than to the MBR, when it is asked to install to '(hd0)'. In Ubuntu 7.04, however, the behavior is normal, as grub-install installs to the MBR with the command grub-install '(hd0)' and grub-install /dev/sda
Also, for some reason, when entering:
sudo grub-install '(hd0)'
The following error is returned:
