I was happy with 12.10 Ubuntu, it's messed up when I tried to upgrade to 14.4 I was able to download latest version 14.4 . However it did not not us partition and it is blended with window's program file.

I am trying delete it : tried windows to reset earlier date and it was no help. Someone suggest find the root program stored ( no idea what that means and how to do) and delete it.

Right now I have Window 7 home and want to upgrade to window 7 professional. Any advise?

Any ADVISE ? Thank you.
