In Bootcamp my Mac starts up in Windows and I can't switch to OS X HELP
I recently took out the hard drive to clean the Mac Pro from dust and after I've put it back the Bootcamp started in Windows. Now I can't switch it back to OSX and when I go to the Bootcamp control panel in Windows it doesn't show me the OSX drive as one of the mount options. How do I fix it?
Mac Pro, Mac OS X (10.7.2)
