How to fix MacBook Pro’s grey flashing folder?

My Two-year-old MacBook Pro is flashing a grey folder with a white question mark over a grey background. I cannot get it to do anything else. How do I resolve this? Is it a virus?

  1. It sounds like OS X isn’t able to find a bootable drive. There may be a problem with your hard drive or your installation of OS X.


    If that doesn’t help, boot into your restore disk and try to do an archive and install.

    I recommend calling Apple if you got an extended warranty.
