I couldn t find a solution since maybe 5 hours. I have checked everything on Internet. Here is my problem,
I dual booted Ubuntu 14.02 beside windows 7. I removed windows 's files accidentally. I went on with ubuntu. Today It said there isn t enough disk space. So I tried everything to fix it.
Finally I want to delete everything and reinstall ubuntu. But nothing seems to work. Please help.
I have a bootable usb with iso file of ubuntu 14.02. Everytime I restart I just see 5 options, none of them is working.
