Comment 36 for bug 8497

In my case the drive that is seen by grub as (hd1) when the system is running appears as (hd0) to grub during bootup.

As a workaround I opened /boot/grub/menu.lst and changed the 'groot' line to rea:

# groot=(hd0,0)

Note that the line is supposed to stay commented out. The 'update-grub' tool actually reads these commented values when it is generating a new /boot/grub/menu.lst.

This way I don't have to remember to change (hd1,0) to (hd0,0) after every automatic menu.lst update.
