I'm unable to select macintosh hd as my startup disk
I am running 10.8.3 and have Boot Camp running Windows 7 on a Retina MBP 15" 2012 model. I am unable to select Macintosh HD as my startup disk as it is not even listed in the options. I've done some searching and I don't see anyone with the same issue. If anyone can help it would be much appreciated, and if I left out some information you need to help me just say the word. I'm unable to install the latest SMC update until I get this fixed it looks like.
MacBook Pro with Retina display, OS X Mountain Lion (10.8.3)
