Got as far as MultiBeast - Now just Black Screen

[forkenbrock]

I had a Mavericks installation using a gigabyte ga-z77-up4 th board and R9 270x card. It was working just fine. I started the Yosemite upgrade process and was able to boot with the USB stick to run MultiBeast. I installed MultiBeast to the drive, but when I try to boot it I get either a black screen with a white cursor and line of color at the top or random letters and symbols with a flashing cursor. Here are the settings I chose. I tried System Definitions 3,1 and 6,1 the first two times I ran MultiBeast.

I will close this thread and post in the Graphics forum. It seems the problem was my XFX 270X graphics card. I was able to boot the installation with internal graphics after changing the profile to MacPro 6,1. However, when I insert the graphics card it boots to a black screen, with a line of color and white cursor at the top.
