Ok so i got my macbook back from apple after a repair and i booted it. OSX loaded fine that time so apple can't have caused it. But i loaded with bootcamp into windows because i play games on windows. While using windows it blue screened. So i got fed up with windows and tried to load into osx. I got the apple symbol on boot and the spinnning loading thing but it would go no further (i waited 15 minutes. It normally takes 30 seconds). I used Command+Option -S. And used fsck -fy. This is what it said. I figured this would get me nowhere so i booted into windows with boot camp which still worked and typed this up. PS: I used disk utility from my install disc and it would not mount Macintosh HD which was unmounted.
