I can't boot up the installer of Mac OS X Lion.
I have a Dell Latitude D630 with Nvidia Graphics.
It has a Core 2 Duo with Nvidia Quadro 135m
This is what happens when I try to boot up from the USB installer.

What stage of the install process are you at according to this guide: http://tonymacx86.blogspot.com/2011/10/unibeast-install-mac-os-x-lion-using.html
I am on step 3. The Unibeast installer will not boot.
I am having this same issue with my sandy bridge system that has never had any issue booting in the past. I am currently stuck on [PCI configuration begin]
gigabyte H61 USB3
GT 640
i5 2500k
I have tried all combinations of PCIRootUID=0/1 and npci=0x2000/0x3000. In the past all the system needed to boot was PCIRootUID=0 GraphicsEnabler=No npci=0x3000 (lion through mavericks). kext-dev-mode=1 and IGPEnabler=Yes both seem new to this round of MB. I have tried their revereses as well in the boot flags with no success. Would love love love some help here. I feel like I am really close, would much prefer to have yosemite on this system then reverting back to mavericks for the long run.
Thanks
