Installation issue

I am trying to install debian on my mid 2012 macbook pro and have a dual boot system. I have downloaded the live CD amd64 7.4 gnome iso and have tried to boot from it. My processor is a core i7. It boots, but only a black screen with a line comes up. Does anyone know what the problem is?
