Thanks for your reply. I managed to boot off an ubuntu live cd (lvm named differently) and get the device properly mapped, booting with the drive plugged in the usb port worked (as you say mount /dev/VolGroup...etc). My next step will be trying to rename the volume group (vgrename suggestions welcome). If I don't damage it, then I will try to put it back in the pc and boot and see what I get.
