Temperamental GRUB behavior after hard restart


So I upgraded from openSUSE 10.1 to 10.2 recently, and it works beautifully. Love it. Got Beryl up and running too, thought it crash every so often (and i expect that). But my problem now is that I can't get to SUSE anymore. After a hard restart (no proper shutdown), grub has been terribly temperamental - sometimes it (grub) loads, sometimes it doesn't, and sometimes when it does, it's very slow. I want to be clear - SUSE boots fine, Windows boots fine, but Grub does not load more often than not. I unplugged my Linux drive and I can get into Windows, but I want to be able to get back into SUSE (especially since i have no intention of upgrading to Vista).

To be clear again - I've mounted my Linux drive after booting from a rescue cd, fsck'd the linux drive several times, checked both menu.lst and device.map - everything on that front is perfect. My problem is that grub simply does not load - comp tries to boot from CD-ROM, then goes to read the harddrive and stops - no "Grub Stage 1.5 loading" type message or anything. Once I load any OS, I can read the drive fine. Could the problem be in the swap or the MBR? I've run out of ideas, and I don't have any floppy disks from after 1993, so attempts at creating a grub only bootdisk have been futile.

Please help!

Thanks

You didn't say if you reinstalled the grub, so:
Two things:
First, I've seen boxes with that grub behaviour after a sudden shutdown (not unmounting the partitions properly).

Second, to reinstall grub:
boot from that rescuecd
[ assuming your root partition is in /dev/hda5 and the mountpoints in /mnt ]:
# mount /mnt/hda5
# chroot /mnt/hda5
# grub-install hd0 (will reinstall grub in first disk, hd1 in second, look the content of /boot/grub/device.map if needed)
