I had a failing IDE HD as /dev/sda, so I installed 10.3 on a new SATA

top of the screen.
Booted from DVD to rescue, altered fstab and menu.lst was changed
from (hd1,0) to (hd0,0), still won't boot and grub commands give
unrecognised device string errors.
menu.lst now says
gfxmenu (hd0,0)/boot/message
No luck.
Rescue isn't as easy as it used to be. The solution in
http://lists.opensuse.org/opensuse-factory/2007-04/msg00048.html
might be
your solution.
Did all that, /dev/disk/by-* tree is sound, looked up "info grub" and
"info grub-install", nothing makes any sense.
# grub-install /dev/sda1
# grub-install /dev/sda
# grub-install (hd0)
# grub-install (hd0,0)
grub> setup --stage2=/boot/grub/stage2 (hd0)
grub> setup --stage2=/boot/grub/stage2 (hd0,0)
and other combinations using /dev/sda and /de/sda1 all give "Error 12:
Invalid device requested".
The odd thing is that when I had the IDE drive installed (/dev/sda) with
the SATA (/dev/sdb), it booted off /dev/sdb, after removing the IDE
drive, it refused to boot. "fdisk -l /dev/sda" shows the bootable flag
on /dev/sda1. I have / and a swap partition on the drive.
I can't think of any incantation that will make grub do anything.

Regards
Sid.
Shouldn't be necessary because you switch the disks, but, did you check
device.map ?
Regards.

I certainly did and it is the same before and after the problem was
fixed. I also had removed the line "(hd1) /dev/sdb)".
(fd0) /dev/fd0
(hd0) /dev/sda
I'm perplexed as to why simply removing the IDE drive would cause the
SATA drive to suddenly not boot, must have been something in the stages.
Coming to this party a little late, but the reason why the SATA drive
wouldn't boot is because by removing the IDE drive, you changed the
device name for the SATA drive. It went from hd1/sdb to hd0/sda, and so
everywhere GRUB was looking for hd1 or sdb had to be changed to match
the new disk layout.
I wrote up a short bit about restoring grub here, after they messed with
the easy page found on the ubuntu wiki:
http://linuxbraindump.org/2007/08/17/restoring-grub
Of course, this just allows you to boot grub. You will also have to
edit the menu.lst file for it to find the new locations.
I found what I wanted on the Ubuntu wiki when pointed in that direction,
then I asked myself why I didn't google for an answer - probably at
04:00 you are never as smart as after you've been to bed.
Thanks and Regards
Sid.
