snow leopard(10.6.5)freezes on startup with bootcamp and windows7 Help! I've installed boot camp and Windows 7 on my black Macbook Santa Rosa (2.4Ghz, 4GB RAM) and have a serious problem where I can no longer boot into OSX.
OSX freezes with the apple logo and timer, but also has an extra progress bar that I have not seen before.

Has anyone else encountered or heard of this problem?

This is the second time that this exact thing has happened (the last time I just reinstalled everything, as I wanted to increase the size of the windows partition anyway), but really don't have the time to go through all of that again.
The first time that this happened, I ran disk utility from the Snow Leopard disk, and attempted to verify permissions and disk but to no avail.

Any help would be most appreciated...
Can you start it in Safe Mode?
