I have no idea what I'm doing.

I'm new to hackintosh and want to know how to install Mountain Lion on to my Windows 7 PC as a dual boot.
I have never installed any OSX on to my computer so I really don't know where to start and where to end.
I read a few blogs about it and what I have heard is that I must have an already installation of any OSX such as Snow Leopard or Lion.
Then I am able to purchase Mountain Lion for $20 on the mac store and upgrade the OSX to Mountain Lion.

I will be purchasing the upgrade of Mountain Lion instead of downloading it somewhere.
But if there is a good working download somewhere for Rapidshare that actually works. Pm me I like free shit.

I'm not sure if my PC is compatible. Here are the specs :

Operating System : Windows 7 Ultimate - Service Pack 1 - ( 64 BIT )
Processor : AMD Bulldozer FX-8150 3.60GHZ
RAM : 8GB Ram Kingston HyperX
Graphics Card : NVIDIA GeForce 8800 GTX
Power Supply : 700W OCZ MOD XSTREAM-PRO
Mother Board : ASUS M5 A99X EVO
128gb SSD OCZ Vertex 4
320gb HDD

I have a premium Rapidshare account so I am able to download any OSX if I need too.
I would also like if someone could recommend a video of a latest working Windows 7 Mountain Lion installation guide (or text from a website)

I'm not quite sure about the dual boot but I do know someone who knows how to dualboot OS's so I guess I'm good but if there is a tutorial for dualbooting Mountain Lion please PM me or post it in this thread.

Thanks for reading!
