I need help trying to install MAC OSX Snow Leopard on my HP DV6T.

Here are the specs:

Intel(R) Core(TM) i5-430M Dual Core processor (2.26GHz, 3MB L2 Cache) with Turbo Boost up to 2.53GHz
RAM: 4GB DDR3 System Memory
WINDOWS 7

I have a friend that is going to put Snow Leopard on a CD or a Flash Drive(If possible)

So can someone find me a tutorial on this one? Kind of new to changing things with computers. Sorry :/

Also, I was wondering if is it possible to just turn the OS of the laptop to MAC? instead of having dual-booting?
