Yosemite Install Problems Can't get to install OS X Screen

Hi All. I went out and got all mostly all recommended components thinking the install would have no problems however I can't seem to get to the OS X install screen. I tried just launching straight unibeast but the it doesn't even load 1/4 of the way. I tried -v and it loads and hangs on "still waiting for root devices". Some successful installs say they use GraphicsEnabler=Yes maxmem=4096 and npci=0x2000 but I'm not sure how to enter these commands. Do you type them all after -v??
I set up the bios as recommended( disable VT-D and onboard graphics, Set other OS ) I'm sure this is an easy fix since I have mostly recommend components. Any help would be greatly appreciated.

Not Yet, I wish it was. Going to change Title and maybe get more attention.

You might try installing using your integrated graphics instead of the discrete card and see if that makes a difference.

If not, try adding npci=0x3000 to your boot flags or even PCIRootUID=1 npci=0x3000

Thanks That got me to the install screen and so far so good but let me ask a question. Since I will eventually being using a graphics car should I be installing with GraphicsEnabler=Yes PCIRootUID=1npci=0x2000 to a boot flag? Should I lead off boot flag with -v?

I am able to install OS X however I now can not get Customac to boot after Multibeast. I did just a straight install of Unibeast then used the Multibeast settings shown below. Now when I boot I get to apple screen and after about 5 seconds it just reboots never starting to load. Not sure why Bios is showing two different versions of my HD
