This are grub fixes to servers that are not booting up due to improper entries in the grub menu.

grub --batch <<END
root (hd0,0)
setup (hd0,0)
quit
END
#
sed -i 's/dev\/sda/dev\/hda/' /boot/grub/device.map
sed -i 's/(hd0)/(hd0,0)/' /boot/grub/menu.lst

The fix includes replacing (hd0) with (hd0,0) and /dev/sda with /dev/hda.
