Hi all, I just restarted my macbook pro because my camera was not working and I got a really strange and worrying screen...... It was a grey screen and it had two options - One was MAcbook HD and the other said Recovery and both had images of a Hardisk. Then below I could select a wireless network... What the hell is this?? I just restarted the macbook.......What does this mean?? I selected Macbook HD and no wireless network and it started up ok.... I havent upgraded my OS to mavericks......does anyone know what this could be and why it happened?? Anything I can do to check all is ok?? Thanks!
