I upgrade from ubuntu 11.04 to 11.10 during its beta stage, and everything was working great despite a couple error messages. But suddenly LightDM started acting up, when I would type my password to log in the screen would flash and bring me straight back to LightDM.
Then one day I booted to a message similar to "GNU grub version 1.99 ubuntu. Minimal BASH-like editing is supported. Type help for complete list."
I reasoned I messed things up, thus I took a live CD to simply copy all my files to an external hard drive so I could reinstall Ubuntu. But when I go to my root folder there is only boot/grub/etc.
I recall my home folder became encrypted by it's self prior to this error.
How can I get all my data back? Thats all I'm concerned about, not so much about reviving Ubuntu, I will simply reinstall it.
