Improperly installed Windows 7 on my Macbook Pro

I am on a Macbook Pro running Snow Leopard and used Boot Camp 3.0.4 to try and get Windows 7 on it. I partitioned the hard drive and successfully installed Windows 7 on my comp using my Windows 7 CD. However, I did so without ensuring that I have a Snow Leopard CD. So now I am stuck in Windows. Anybody got any solutions for a dumb man? Also, if I end up needing to get a new disc, to complete the Windows 7-Snow Leopard installation, will I lose the files I had on the Mac OS?

In Windows 7, just launch the bootcamp manager, and select restart in OS X. Or, while booting, hold down the Option key and select OS X when it appears. Installing Windows via bootcamp does not erase OS X.

Zoolook, since he doesn't have the Snow Leopard CD handy, chances are he doesn't have the Boot Camp support software for Windows installed.

OP: If that's correct, you'll need to shut down the machine. Turn it back on and immediately press and hold the Option key. Continue holding until you're presented with a choice as to which partition you want to boot from. Choose 'Macintosh HD' and it should boot into OS X.

Once you get your Snow Leopard disc, you'll want to boot into Windows the same way... then, pop in the disc and install the Boot Camp package for Windows.

Oops, I said command key, but it's Option key, thanks for the correction. It's been a while since I used bootcamp.

You should be able to download bootcamp 3.x from Apple's site though.
