Reinstall Ubuntu through a LiveDVD/LiveUSB, when you start the install processes you will be asked if you want to "Reinstall Ubuntu", and keep your files, or "Erase Ubuntu and reinstall" getting everything fresh and new (Everything will be deleted).
I recommend you to Erase your Ubuntu and reinstall, deleting everything, although if you need to keep your files and there is no way to backup them, then just choose to reinstall Ubuntu.
Things should be solved then!
