Dual Boot Windows 7 and Snow Leopard

Anyone on here know how to do this
if I am already running windows 7 ?
Its on a HP Zbook

you have to go into windows disk utility (i think that’s what it’s called) and create a partition for mac os. 40gb should do fine. You also have to make sure your computer is compatible with hackintosh. if your computer is compatible you can launch the hackintosh installer but DO NOT OVERWRITE YOUR WINDOWS 7. after that mac os will install and boot into mac os. if it doesn’t boot into mac os open the boot menu (usually F11) and choose mac os. once it starts up you may get a prompt to connect a bluetooth keyboard. hit space on this prompt and go through setup as normal.
