I had Ubuntu 13.04 dual booted with Windows 7. I tried to upgrade to 13.10 using the software manager. However after the downloading stage i.e. Fetching new Packages my system shutdown somehow and the process was not complete. After having restarted it I am not able to access my hard drive through Ubuntu and neither am I able to open any applications. When I check the About this Computer it says that I have Ubuntu 13.10. I try opening the applications using Alt-F2 but every application I open crashes after some time. So is there any way to complete the upgrade process? I'm new to ubuntu so have very little idea.

Theoretically your system could be fixed but it will take time. If you are willing, you can run sudo dpkg --configure -a and sudo dpkg -C, then do sudo apt-get check. Edit your question and post the results of each one. – Braiam Feb 18 '14 at 3:45
@Braiam I tried the dpkg option using the Recovery Mode, but in vain. Nothing changes. Do I try it now after a normal boot? – fts Feb 18 '14 at 3:48
did you made the other ones too? what are the results? – Braiam Feb 18 '14 at 4:35

I used the method suggested by @braiam above. As I have already mentioned, after I restarted my system I was not able to access any applications. So I used the Alt+F2 command and then entered update-manager in the text box and checked the Run in Terminal option. The manager didn't run but I was able to open a new terminal window this way. Then I did what was suggested above and everything was fine.
