I upgraded from 13.04 to 13.10 and shutdown my computer and now it boots to a blank screen everytime. The only thing there is a cross shaped cursor. I can boot to terminal using ctrl+alt+f1.

Boot repair did nothing ( and when I tried to re-install using a live CD the installation was not detected so I have no option to keep my files.

Is there anyway I can repair without losing my files in my home folder? Thanks.

Your system partition is broken. Boot on an Ubuntu 13.10 disk, choose "Try Ubuntu", and fix your system files this way:

Upgrading from 13.04 to 13.10 isn't supported natively, due to the way that unsupported releases are strung together.

Ideally, you should do-release-upgrade from the current version to the latest version, as each step will (in theory) do upgrade steps needed.

The other alternative is to do a fresh install using a currently supported release, and restore from backup.

It's generally a very bad idea to attempt to upgrade from one unsupported release to another.

You're inattentive. The question was asked on Nov 4 '13, when both 13.04 and 13.10 were being supported! – user300458 Jan 2 '15 at 2:34
Good catch, thanks! I only saw the "edited" date of 9 July, 2014. – K. Darien Freeheart Jan 2 '15 at 3:00
