    Hold the option key while booting and select your OS X partition and press enter. When installing Windows, it sets itself as default boot volume so when in OS X, open System Preferences and go to Startup Disk and select your OS X partition and click reboot

    Along with what Hellhammer said, if you install the apple bootcamp utilities in windows, it will give you a start up disk control panel, where you can set the start up disk.

    Likewise if you want to ensure that OSX is the default start up OS, just choose that preference (in osx) and select the OSX partition.

    Thanks for your kind reply! For a moment I panicked! I thought I'd lost all my Mac stuff! ;-) Silly me.

    Thanks for the useful tips! Much obliged!

    Hi,

    I tried Windows 7 for 10 minutes, didn't like it so decided to uninstall it straight away. Went into Boot Camp Assistant and deleted the partition.

    The problem is that every time I restart the MacBook Pro, it tries to boot from the Windows partition (which doesn't exist anymore!), so I have to press the Option key and select the Mac partition...

    How can I change the boot options so that it boots from the only existing one, the Mac partition?

    Wow, serious, buddy. Use punctuations.

    So in short:
    System Preferences > (System) > Startup Disk.

    Here you can simply select which disk your system chooses to boot from by default. Restart your machine to accept the changes.

    If you aren't logged in as administrator, you have to unlock the pane by clicking the lock on the bottom left of the pane. If you are logged in as administrator, this isn't necessary.

    Hold down the option key when you boot and you will get the option to boot OS X or Windows. You can then change the startup disk preferences as mentioned earlier in this thread if you need to.
