Windows 7 - Dual booting with mac osx

Hi, I have a windows 7 ultimate pc, and would like to know if there is a way to dual boot windows 7 without buying new hardware, and if not, i would like to know if there is a program that can be downloaded for free, that can do it. Also, i would like to know if there is a place where mac os can be downloaded for free, though I would be fine buying a copy.

There are a ton of walkthroughs and instructions on dual booting,, trust me, you will not lack the absolute wealth of info through google or bing.

As for MAC OS X,,, you can not legally install OS X on non-apple hardware, It is a violation of their EULA.
Can it be done? Yes.
Are you allowed to? Nope.

My brother has established a way to get OS X onto he PC

but i dont know the secret

Dual boot Windows 7 and osx, it's not secret

Getting closer.. (Dual boot W7 and OSX)

I have personally installed OSX in my desktop. I have used the version called as iDeneb. It is a long, lenthy and complicated process. I succeeded in it after umpteen times, but still sound and internet doesnt work. So it is sitting idle in my desktop along with XP.

I configured dual boot, but it doesnt work. Have to boot thru the OSX DVD.
