Clear your apt cache

sudo apt-get clean

Install Ubuntu desktop and force a re-install

sudo apt-get install --reinstall ubuntu-desktop

This will install all the packages necessary from the desktop to run, you should see Ubuntu as an option next time you reboot.

I honestly didn't expect the solution to be so straight forward and fast as this. Muito obrigado, Bruno! – Digger Oct 20 '11 at 22:54
did it work? :D – Bruno Pereira Oct 20 '11 at 22:54
Like a charm! Thank you a lot! – Digger Oct 23 '11 at 14:32
wlcm, really happy it was that easy ;) – Bruno Pereira Oct 23 '11 at 14:35

I had a similar problem when running the beta version of 11.10. What I did was go into the software center and search for Unity, uninstall then re install it with all the add-ons listed.

If that doesn't work, try running "sudo apt-get update" and "sudo apt-get upgrade".
