emin3m,

Welcome to the Ubuntu forums.

You may or may not have a recoverable system, but for us to have any chance of knowing please download and extract the boot info script, run it, and post the contents of RESULTS.txt.

Click on the BIS link in my signature line to go to the script page.

Added: You would do this from the Ubuntu LiveCD. Also, an 'out of disk' message may mean your BIOS is limited to seeing only a certain portion of your drive. On boot, you might open the BIOS setup and see what the system reports as your hard drive size (for the Ubuntu drive, if you have more than one).
