Forgot to say that I'm trying the 64 bit version.
*EDIT
This is the simplest way to describe my experience:
After that I tried running in compatibility mode, where I got a terminal. I did startX and it said fatal error. No screen found.
My graphics card is an Nvidia GTS 250M, also there was another person on the help chat channel who was having the same issue as well.
I've tried re-downloading the .iso and reinstalling it to a different USB. Same problem.
