I tried to upgrade from 13.04 to Ubuntu 13.10 but while I was upgrading the internet connection cut-off and I wasn't able to resume it.
A couple of days later I was trying to install another package on Ubuntu 13.10 and it took about 1 hour, after I finished installing it The computer restarted and I found it has Upgraded to Ubuntu 13.10.
Here My problem starts. First, The menu bar disappeared, then I whenever I open the dash it keeps on loading without viewing any icons. I'm not able to change sound, Networking, and brightness settings.
I'm not able to to install or remove any package, I'm not even authorized to view my packages. Also I'm not authorized to complete Ubuntu 13.10 installation, and when I tried to re-install Ubuntu 13.04 Which I have stored on a USB I found that I can't access usb or Dvd on the computer.
I'm not authorized to do anything, Please Help!
