Then I would expect to do chroot /mnt/sysimage The resuce mode boot already has copies of grub and other things in the rescue boot image, and the raw disk devices are there even if I don't mount them. Grub only needs access to the disk device to write the MBR, not any mounted partitions. These instructions do assume that your original /boot partition and all the kernel images and grub config files are still there on whatever (hd0,0) maps too. If they've been clobbered as well, these instructions won't help much. In that case you'll need to mount the disks and restore them from back (you do have backups, right? :-).
