As you know, if you hold the Option key down while booting, you get to select either Windows or OS X from the dual-boot that comes up. If selecting OS X doesn't work, you may need to un-install your Windows and Boot Camp to re-enable OS X. Possible you may have to reinstall OS X.

I hope you have a pre-Boot Camp backup...

Don't do it quite yet, though. Someone else may have a better answer for you...
