Grey Screen: "You must restart your computer."

I just purchased Windows 7 to dual-boot on my brand new 2010 MBP. After I installed Windows 7, I inserted my MacOSX Snow Leopard install DVD so I could install the drivers. A message came up saying "This installation isn't compatible with this computer". So I restarted my computer and when it was booting up it gets stuck at the grey screen with the apple logo and rotating wheel. After a while a grey curtain comes down with a Power Icon in the background and a window saying "You must restart your computer" in a variety in languages. I tried restarting and the same screen comes up every time. I've tried all the boot key commands such as holding shift. But each time it doesn't recognize it and proceeds to the grey screen of death. I'm completely stuck here and need help ASAP. I would like to do a hard reset on my MBP, but I can't since I can't boot to MacOSX and when I boot to Windows 7, it runs for about 2 minutes and completely freezes, causing me to force restart. Any help is appreciated, thanks.
 
Don't you have to partition the hard drive first before installing two operating systems, and don't you have to install Mac OS first?
