So, the other night my macbook froze so I held down the button to shut it off. Then when I tried to turn it on I am stuck at the apple logo screen. It stays on that forever. I left it for over an hour and it was still like that so I shut it off removed the battery and left it like that overnight. In the morning it was still the same! Is this related to my hard drive? Also, I had a disc stuck so I thought it was that but I got it removed so now it's still stuck on the screen when I turn it on. Please help me! I'm a little nervous! Thanks so much in advance!
