I'm so sorry this is late! I couldn't get into my Ubuntu or Windows with my GPU.
Firstly I want to say thank you for taking the time to help me with this problem, I appreciate it. Secondly, I would like like to ask if you have a detailed guide I can follow to do those things? I've never uninstalled kernels or Nouveu (at least not without a problem).
I'm currently running driver 306.64, just to tell you, with no GPU.
