Is it possible to install Snow Leopard/Leopard inside Windows?

Hey, I've got Windows 7 at the moment and was looking to make my laptop into a Hackintosh. Don't ask if it's compatiable or not, if it isn't I'll just re-install Windows, my loss if it isn't compatiable right?

Anyway, I've got no dual-layer discs so I was wondering is it possible to run the installtion inside Windows 7 and wipe my Windows 7 installtion whilst installing Snow Leopard or Leopard which ever one I choose - I don't know the difference. :S

Or could I keep my Windows 7 installation and dual-boot by installing it from within Windows? :S

Thanks for any help,
Stylah.

bump...........

You can't "wipe windows install while running windows" that is a paradox.

The only way to run the snow leopard install from within windows is to run the install in a virtual machine (for example the free VirtualBox)

What about if I made a partition with nothing on it?
Could I install it from within Windows then?
