Need help with install on Lenovo x201 Laptop

Hi, I've been trying to get Yosemite on my Lenovo x201 laptop and I'm running into some issues. I am using the guide and kexts provided on this website http://forum.osxlatitude.com/index....n-lenovo-thinkpad-x201s-and-maybe-x201/page-2 but it isn't working. I use unibeast to create my Yosemite Laptop install and boot it up on the laptop but after it finishes loading the kexts in the boot loader the screen goes black and it restarts.

I have the BIOS...
