    I just partitioned my drive so I now have Snow Leopard OS on Macintosh HD and Mountain Lion OS on my new partition called Mountain Lion. when I boot from power on, it boots to Mountain lion by default. Anyone know how to change the default so it boots to Snow Leopard? :confused:

    System Preferences > Startup Disk.
    "Select the system you want to use to start up your computer"


    Starting up with the Option Key held down allows you to select which system to boot during the start up process.
