Ok, so I installed Ubuntu 11.04 on my hard drive, have a bunch of files on there with no backup(Stupid I know) I upgraded it to 11.10 via the update manager. It worked for awhile, but then it stopped booting. I would choose to boot to Ubuntu and I would get the following error message:
un-int: /sbin/init: I/O error
It just freezes here and I cannot do anything but restart the system, which still will not allow me to boot. I tried to put the install disk in and repair it, but still no luck. I also tried to load the system as an external drive to get the files, but nearly all the files are locked saying I do not have access to them. I just need the files, I am not concerned with saving the OS, please help!
