I have just upgraded my installation of Ubuntu 12.04 beta, and now I won't start the GUI. If I go into "Previous versions of Linux" from the boot-menu I can start the old upgrade without problems. The one that doesn't works runs kernel 3.2.0-23-generic. The one that works is running 3.2.0-22-generic.
What I'm asking is how to either fix the upgraded version, or make it disappear (at least from the listing) so I don't how to mess around in grub when I boot my computer. Thanks.
