Actually a mac os doesnt run on windows pc. However, there are some "Hackintosh" OS (mac os hacked for windows) are available in internet, but I dont think they will run flawlessly.
If you wanna try 2 os in your pc, you can try win 8, 7, ubuntu, steam whatever you want. But an original mac os cant be run on windows pc afaik.
note: windows os can be run on mac pc.
