    Basically, I was trying to install Windows 8 Consumer Preview onto my Macbook Pro (It's running Snow Leopard). Which, I found to be too difficult, so I wiped my Bootcamp partition, and started over with Windows 7.

    Now, I did wipe the Bootcamp partition and reinstall Windows quite a few times (Maybe 5-6?) [ it didn't work perfectly at first].

    However, ever since the last time, OSX doesn't boot up anymore. When I choose the Macintosh HD at startup (Holding option while turning on), it goes to the silver Apple logo, and the spinning circle underneath it indefinitely.

    Windows, however, boots up fine. Any ideas?
