I am running an alternate install of Ubuntu 11.10. I just ran the latest update which required a re-boot. When I rebooted, my desktop stops at the POST (Power on self test). My computer is set up with Logical volumes (which is why I used the alternated install).
I cannot get to the boot (grub) prompt. I can load the Ubuntu Live CD and see my first drive (40 GB) but cannot access my logical volumes.
I am still somewhat new to linuc and need help. How can I get this desktop to working again without losing my very valuable (and not backed up) information?
