I am stuck between version 10.04 and 10.10 of Ubuntu . I started upgrading when the computer cashed; now I can not boot back to the hard drive. I am currently up on a live 10.10 cd. How can I proceed?

As a side note I would prefer not having to reformat the hard drive as for I have a few files that I need to affirm that I have backups of.

In such situation Fresh Install would be better option and Back up your few files to cloud ( if no other storage ) from live cd if possible .And try 12.04 for fresh install . – atenz Jul 27 '12 at 15:33

You might try dropping into a shell and chrooting to rescue the installation. Here's a link:

You could boot into a rescue shell, or use the CD. If you use the CD, make sure you mount all your partitions. Then open a terminal and chroot to your installation: ie, type (replace with appropriate path):

chroot [pathtoMountedInstallation] /bin/bash

That will change the terminal to think that your installation is the root. Then you can:

sudo dpkg --configure
sudo apt-get update
sudo apt-get dist-upgrade

Hopefully that will work, but it may depend on when the upgrade failed.
