Help! I get a black screen after installing OSX!

Question

I choose to install iAtkos ML2 on my computer. I successfully installed it but when I reboot into OSX I get greeted with some music and a BLACK SCREEN and the monitor lost signal. I am assuming this is a problem with my video card, so I reboot back into my Windows partition and use TransMac to navigate my OSX drive. I find a kext file for the video card I am using and decide to drop that into the System/Library/Extentions folder. I deleted all of the cached kext files and rebooted to no avail. Of course I tried all kinds of boot flags without any success. Single user mode wont start neither will safe mode.

Because my mobo is Dual UEFI I decide to use iAtkos ML3. I install OSX and get the same problem after the installation. I had no idea how to use the Clover boot loader at all so I could not try any bootloader flags.sad.png

Here are my system specs:
Motherboard: Gigabyte GA-B75M-HD3
Processor: 3rd Gen Intel Core i5 3570 4 cores - 3.50Ghz & 3.80Ghz Turbo Broken Integrated Graphics
Graphics Card: Nvidia GeForce GT 630 (MSI brand)
RAM: 16GB of DDR3 Ram distributed into two slots
Network: Realtek PCIe GBE Family controller
Display: Samsung Syncmaster 2494HM and Syncmaster SA450
Sound: Realtek Card
Storage: I am planning to install OSX on a 750 GB HDD
(I have Windows 7 on a ssd and a 2tb storage drive)

I have changed a few BIOS settings
enabled AHCI Sata
disabled Intel Vt-d


Hopefully somebody can help me with this, I want to run Mountain Lion encouragement.png

also I have access to another PC running OSX

DUBZeeD told me that my computer is more compatible with OSX Mavericks than Mountain Lion. Thats great because Mavericks is free and has lots of features!

I told I am unable to boot OSX because my CPU does not have on board graphics.

I gave him my system specs and told him I want to install Mountain Lion

He gave me a BIOS revison thing GA-B75M-D3H (Rev 1.0 - F6)

He told me about Mavericks

He told me that machine is compatible out of the box but will still need a few changes to get things working properly.

We decided to use Clover or MyHack to boot OSX and install OSX

Hopefully that helps? <bluet00th>eagerness.png

Also, will the OSX Mavericks Free from the app store work with U{censored}?

npci=x3000

PCIRootUID=0 or 1

-v

-f

-s

and any other flags
