[ILUG] More grub-related pain

[gregwm]

well it boots into grub, so the mbr is working.  looks like either the
specified kernel is missing, or mis-specified.  can you boot the older grub
entries?  also perhaps possible your mbr is sending you to a grub.conf (or
menu.lst or grub.cfg depending on your distribution) in a different
partition than you expect..  grub.conf is easy to edit, eg from a live CD.
 and if perchance your current mbr is going to the wrong grub.conf, the
quickest fix is put a "configfile" entry there to jump to the right
grub.conf, eg
title jump..
uuid <filesystem-uuid>
configfile /grub/grub.conf
