Re: My files are gone
That depends on how you did the install (entire disk?). You can list all your partitions with the command:
In case the NTFS partitions are all gone and you definitely need data that was one there: STOP USING THE DISK and start Ubuntu from a Live CD. From there you can run recovery tools like Photorec. Chances are (some of) the data is still somewhere on the disks but you need recovery software to obtain it.
