get advanced supergrub or lilo depending on which you use to load mbr.
you may need a good live cd like knoppix to be able to edit and fix partitions and menu files before starting the boot.

Just boot to the previous kernel and then modify the grub menu, will be fine.
(At the beginning I try to use linux rescue and manually mount /dev/sda2 /mnt/sysimage, but fail,maybe because we use hardware RAID,no time to check it out so use the above option)
