Running Red Hat ES4


Hi, have attempted to update the kernal/initrd 2.6.9-78.0.22.EL but am unable to boot the system. Booting an older kernal boots the sytem wihout any issues (2.6.9-67.EL).

On boot up receive the folloingerror message;

mkrootdev : label / not found

A copy of my Grub config is below.

# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

Anyone got any advice?
