I have an iMac (late 2009) and it originally had Snow Leopard installed on it until recently when I did an upgrade to Mountain Lion. Anyway I have a problem since upgrading as now in Mountain Lion I cannot see the Bootcamp (Windows 7 64bit) disk icon on desktop. When I go into disk utility I can see the Bootcamp disk but it is greyed out. I have tried mounting it on disk utility but I am unable to as it comes back with errors that it cannot mount disk. Anyway the strange thing is that when I reboot my iMac and press the "alt" key to get to select the Windows 7 disk, I am able to boot into Windows 7 normally which is odd considering the Bootcamp disk is greyed out on Disk Utility and I cannot mount it. Please advise.
