Storage

I hate to sound like a wimp, but fiddling with dual-boot options is like running naked through barbed wire. Can really be painful and not always a good idea, especially if it's your 'main laptop', meaning that you may have some data on it.

Hard drives and even USB jump drives are so cheap that having a second drive all loaded up with it's own OS is the safest bet. Or alternately, setup a VMware server and load/install any guest OS you want in it's own happy virtual world.

The plan for me was to take out the hdd with windows 7 and install snow leopard on the other driver alone, then boot using F12. or try using easy bcd to create an entry for snow in the windows.mbr

Should work if you're using a macbook. If you aren't, you can't do it because you'd be violating their terms of service that are themselves in violation of antitrust. Best recommendation, don't bother. There's nothing on OSX that isn't done better on windows.
