When I start up OSX, the wheel spins and it turns blue like normal...but then it turns back to grey and starts to spin again...and then it turns to blue...and it's an endless loop. I'm really scared right now...did I lose everything on OSX? Should I go to an Apple Center? I'm using bootcamp at the moment and I need to get back to OSX because all of my files are there. However, I can easily read everything via "MacDrive" for XP. Please help! Thankee sai.
