[ubuntu] I'm going Crazy!! MBP 3,1 USB install

I've been trying to install ubuntu onto my MBP 3,1.

I've tried either 32bit or 64bit, No Go.
I've tried the Virtual Box methods, No Go.
I've tried using the bootable USB instructions provided by Ubuntu, No Go.

I get a "Secure Boot not Enable" error when I to boot from USB, Then it goes to a screen that lets pick install or try, either install or try ubuntu leads me to a blank screen with nothing!!

I'm officially going crazy!!
