    Hello everyone. I've run into an issue with dual booting on my Mac Pro. I bounce back and forth between OSX and Windows because I'm a musician and gamer. I have the two installed on separate internal drives. I've always used the hold option/alt method during system start up to select which OS/drive to launch. However, it seems I've lost the ability to do that.

    The issue is I installed a new graphic card. It does have native support in Mountain Lion and I've tested it over on that side. Works fine. The problem now is that I overlooked the fact that I set the system to automatically boot into Windows instead of OSX. When I hold option/alt during system start up, I no longer get the screen to select which OS/drive I want to boot. Just get a blank screen and no progress.

    Does anyone have any idea on how to resolve this issue. I really need to be able to get back into OSX to write and record tracks. Thanks in advance.

    If you have loaded the Bootcamp software in Windows (recommended) - then you should have a BootCamp control thingy in the system tray, which will give you the option to restart in OSX. To get back to Windows goto System prefs in OSX and change the startup drive to Windows.

    Pretty simple if your GPU does not support boot screens.

    Sadly, I'm pretty sure that software was not installed on the Windows side when Bootcamp was done. Looks like I was a bonehead and missed that step. Is it something that can be installed now and work correctly?

    In OS X, you can install bootchamp from here. It'll give you a "boot into windows" option on your menubar.

    Do a NVRAM (or PRAM) reset as explained here while starting up. It will reset the default startup drive to your OS X drive.

    Thanks Cal, but the issue is I'm stuck in Windows and can't get back into OSX, although that may be handy when I do get back into OSX :)

    Ah, awesome. I'll do that reset and see how it goes. If that gets me where I need to be, what is recommended for me to jump into Windows from that point? Is what Cal posted the best way to go about it?

    Yeah, I posted that without seeing what you'd added.

    You can download the latest bootcamp drivers here.

    This can be done in windows so that is your way out of the situation :)

    (just to add my support for this solution)
