Package: grub
Version: 0.95+cvs20040624-17
Followup-For: Bug #264506
I've just seen this problem before, but i've just come across it again.
For the benefit of other people struggling with this, IIRC, last time
I worked around this by using a grub-floppy and typing (from the grub prompt)
grub> root (hd0,4)
grub> setup (hd0,4)
Background
==========
I'm installing a new (larger) hard-disk, and restoring my system from backups.
I'm adding a additional debian partition hda5 (cloned from my sarge install
(hda2)
for upgrading to etch). One debian partition is also moving from hda7 -> hda6.
The system is booted from Knoppix 4.0.2

The following procedure worked for hda2 and hda3. (These parttiions where
restored to their previous locations). hda5 and hda6 failed.
/dev/hda5
=========
chroot into hda5 (running from Knoppix 4.0.2 CD)
check /boot/grub/device.map
edit /boot/grub/menu.lst
....
# kopt=root=/dev/hda5 ro
....
# groot=(hd0,4)
....
run update-grub
check /boot/grub/menu.lst
run grub-install
Knoppix:/# grub-install /dev/hda5

Neither re-installing grub nor purging/installing fixes the problem.
Upgrading grub to sid does not fix the problem.
I won't need to fix this for a few days, so if you want more info just ask.
