Cannot boot after upgrade from 10.04 to 10.10

[manny_buret]

I just upgraded Ubuntu 10.04 (32bit) to Ubuntu 10.10 (32bit) desktop edition using Update Manger. After installation, the system restarted and it boots straight into a grub> command line. I cannot but into Ubuntu.

I am currently dual booting with Windows XP. I also fired up a LiveCD session and opened up GParted, but it does not list my Ubuntu partition. It only lists the Windows partition.

Any help is appreciated.

Any error messages appearing during boot? Sign in to the terminal using your usual username/password, then run dmesg and check for error messages. Possibly a problem with your video driver which is preventing X from starting?

You could try removing and re-installing ubuntu-desktop. It's a little drastic, but you shouldn't lose any settings. It will reinstall a lot of packages and should fix your settings. I did this today to fix a much more broken 10.04 to 10.10 upgrade.

From terminal, run:

sudo apt-get remove ubuntu-desktop
sudo apt-get install ubuntu-desktop
sudo reboot
