Grey screen

[rockinroll19]

Hi, I am currently trying to boot up to my Max OSX Snow Leopard but when I try I get a grey screen with the apple logo, a spinning wheel, and what looks like a loading bar. The bar disappears after a while, but the wheel keeps spinning. I have also recently partitioned my hardrive with bootcamp to install Windows 7. Here is what I have tried:

-Safe Boot
-holding Option key
-holding Option, Command, R, and P
-holding C key
-Unplugging computer
-Trying to boot from Snow Leopard disc itself

Booting to Windows 7 seems to work fine, as that is where I am typing this post.

Any other suggestions?? Thanks!

Both of those at the same time should work unless you've got a hardware problem. Not sure why you listed them as separate actions. ?
