Had 10.10, then did today's updates and "no kernel found".

Hi, I had Ubuntu 10.10 installed on my computer (partitioned with Windows), and this morning I updated using the updater. After I installed the updates (I hadn't restarted yet), I put my computer to sleep to go somewhere. I just restarted my computer now to complete the update installation, and when I restarted, when I selected to boot into Ubuntu, it dropped me straight into GRUB, and upon a little exploration, I discovered that it didn't recognize any kernel on my machine.

Any help would be much appreciated -- I'd hate to have to reformat my computer for the third time because of ubuntu being bleh.

Boot a live CD, mount your partitions, and use chroot to update grub. E.g. if you have a dual-boot setup with windows on sda1 and a single ext4 partition for root on sda2, this might look like:
sudo -i
mount /dev/sda2 /mnt
cd /mnt
for f in dev proc sys; do mount -o bind /$f $f; done
chroot .
update-grub
exit
reboot
