Need help to install mac os x
On a Windows machine I assume you expect to virtualize OSX. With that assumption the answer is this:

You cannot legally virtualize Snow Leopard 10.6+ you can virtualize Lion 10.7+ though.

This forum post vaguely details the issues with Apple and OSX Snow Leopard and virtualization.

Furthermore, if you dont care about legality, this may or may not invalidate your license of SnowLeopard but works in Virtual Box
