Giovanni, it is rather obvious that the ghost/restoration procedure went wrong.
My advice to you is to backup all your documents (on cd/dvd, on a different hard drive, on a flash disk, it's up to you). Then download and burn the Hardy iso image, and make a clean install of the system. You can find detailed instructions about the procedure here: https://help.ubuntu.com/community/GraphicalInstall For any further help, you can ask questions at UbuntuForums.
