Hope I didn't just break my system

http://ubuntuforums.org – I was bored, and that is why I just started the upgrade from xubuntu 12.10 to 13.04 on my MAIN MACHINE !! Oops.. probably a bad idea. Hope my machine still boots after the upgrade is finished. Anyone else upgraded their main machine to "Raring Ringtail" without thinking too much? (Hardware)
