Grub Failure when HDD descriptor changes

[Dennis McMurchy]

  Hi,

  I've done a default installation of the GRUB loader in connection with
installing Fedora Core 3.  It worked fine.

  I then changed the configuration of my machine a bit, removing one
HDD, so that the FC3 installation and its /boot/grub directory were
no longer on /dev/sdd1, but on /dev/sdc1.

  Trying to boot yields the four letters: 'GRUB', and then nothing.
The machine just locks up at that point.  This error doesn't seem to be
documented under 'Error Messages'.  

  Realizing that the HDD references in grub.conf would be wrong, I
went in and changed the two references to (hd3,0) to (hd2,0). This
had no effect on the symptoms of the problem.

  So, I went into the FC3 installation again, using the Rescue Console
function on the distribution disk.  I 'chrooted' to /mnt/sysadmin, and
proceeded to try running 'grub-install'.  I get error messages referring
to an unfindable /dev/sdd1, so clearly the grub system is remembering
where it was originally set up from.  It's not clear to me where to go
from here.  

  I hate to go back to LILO, which is clearly inferior, but I can't
afford to have my system broken beyond repair every time I swap an HDD
in or out.

  Hope I'm not wasting your time with this, and that you can point me
in the right direction.

  Cheers, Dennis
