    Hi I hope that someone can help me with this problem.
    I have two drives on my macpro, one with my osx snow leopard and the ,other with windows 7.
    Some how I managed to choose to boot from the windows drive, and now cannot seem to get back to my osx drive.
    I have tried removing the windows drive to try to boot from my Snow leopard disk , using both command r and holding down c during start up , but still canot get back to my osx, I have also tried with both of the drives in place, but nothing seems to work that I have tried, Problem is I just can't seem to find an answer to this or any similar problem in either the forums or on google, so I seem to be stuck with windows on my system and no osx where all of my data is.
    Please, please if you know of a way to solve this let me know.
    Thanks in advance:confused:

    This is the PowerPC forum (Macs older than 2006) but I will try and help you anyway.

    When you turn on your Mac, immediately hold down your OPTN key. Any modern Mac (including our old PowerPC based Macs) has this hardcoded. You'll be shown the drives your Mac can boot from. Once it's done scanning, click on the drive you want then press the right arrow to boot from it.

    Note that the days of the old "C" or "X" keys are long gone. These may work, but they are ancient shortcuts and people really should get in the habit of using the OPTN key to choose what drive to boot from. It's beyond me why Apple never stresses this and allows this ancient info to persist.

    When you boot up, hold the [Option] key. This will give you the ability to choose to boot from your OS X drive.


    When you are in Windows, launch the Boot Camp utility found in the tray at the bottom right of the screen.
