Hey guys, Im a college student. On moving out day I found that some one had thrown out a MacBook Pro. Took it home and realized why. It doesnt start up. It stays on a white screen for about 6 to 8 minutes and then goes to the apple logo and then shows a circle with a slash through it. I try to boot in safe mode and recovery mode but it wont go into those modes. It just repeats the same boot up. Im wondering if there is anything i can do to salvage this laptop or is it done for. Thanks in advance guys.
