Replying to Hackintosh question

I have built a new hackintosh that I am having troubles with when it comes to installing the OS. I have configured my motherboard to the recommended BIOS settings, however upon starting the installation I get the grey apple screen. If you have any suggestions or recommendations as to how to proceed it would be greatly appreciated!

Here is my hardware,
Core™ i7-4930K Processor, 3.40GHz w/ 12MB Cache

GA-X79S-UP5-WIFI w/ DDR3 2133, 7.1 Audio, Dual Gigabit Lan, 3 Way SLI / CrossFireX
