I have a HP Pavilion dv7, with Windows 7 and Ubuntu 13.04 in dualboot. Just recently I updated to 13.10, but there were some packages that didn't get installed properly, I thought this wouldn't be such a problem. When I tried to boot My freshly updated Ubuntu this morning, suddenly about 5 minutes in, my launcher and menu bar disappeared out of nowhere, leaving me unable to do anything, since I couldn't even open a terminal using the shortcut. I did a hard reset, rebooted and had the exact same problem. So I did a hard reset, rebooted in recovery mode and tried to fix the broken packages using the 'dkpg' option. This didn't do very much ad I waited an hour and nothing happened. I could type but not cancel the command or give any other command. I saw no other option than to do het another hard reset. When trying to reboot, my laptop now gives no reaction at all. As in nothing. The ligt doesn't even go on, the screen remains black, nothing happens.
I thought this might be because I did too many hard resets, but I have no idea whether this could be possible.
Since I am a Computer Science student with upcoming Finals this is a very urgent matter for me, and I have no idea what I could do next. Thank you for your time and I hope you can help me out.
