I dont know if there is an easier way to do this but one way i would
try is this:

Pleae note that these steps are from the gentoo handbook (the distro i
used before uubuntu) so they may not work the same - but you might as
well try...

Load a linux live CD (the ubuntu live cd will do fine, alternatively
knoppix etc)
from a terminal:

$:   mkdir /mnt/ubuntu
$:   mount /dev/hdb1 /mnt/ubuntu

(change /dev/hdb1 above to the location of your ubuntu partition)

$:   chroot /mnt/ubuntu
$:   env-update
$:   source /etc/profile

You will now be inside your ubuntu system so doing  cd / will take you
to the root of your installed filesystem, not the live CD filesystem.
env-update and source /etc/profile loads the environemtn variables

from here you can work on your system as normal so the next step would
be to reinstall the kernel.

dpkg remove linux-image
apt-get linux-image

(the above 2 may not be right as i am at work on a win box so cant
check - off the top of my head i think it is right, but the name of
the kernel package might be wrong - anyone else correct me?)
when the kernel is installed again it should have taken care of
updating grub to load the correct image.

I hope this helps, but im working from memory for soemthing i did once
that was above my level then ( and probably still is) at least it might
give yousome pointers...
