I just burned Ubuntu 12.10 x64 to a DVD (cd is too small) and put it in my laptop. When I rebooted, there was a violet screen and that keyboard logo. And then a black screen with _ in top left corner. It won't let me write anything in it. I have HP pavilion G7 1303em.
I ALREADY HAVE WINDOWS 7 x64 ON MY LAPTOP AND I WANT TO INSTALL UBUNTU ALONGSIDE WINDOWS.
