I had an electricity cut while I was upgrading from Ubuntu 10.10 to 11.04, now when booting the system I get the following message:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Any ideas how to solve this?

At the grub boot menu if you type e to
edit
the grub configuration for the line you've selected you'll see a line something like this:The culprit is the
root=UUID=ddbfffc1-731c-4931-9129-75c5f42f8ecb
part which probably still has the old UUID or partition listed. If you know the specific partition you can either set it to something likeroot=/dev/sda1
(or whatever your partition number is) and then type ctrl-x to boot or you can substitute the correct UUID which you can find by booting with a rescue disk and running theblkid
command.If you're lucky and your root partition has been properly labeled then you could also try
root=LABEL=/
