    I have two issues in dual booting my 2010 Mac Pro in El Capitan and Snow Leopard. I installed El Capitan first, then partitioned the same boot drive to also run Snow Leopard. Both run fine except...

    1. Everytime I turn on the machine it boots into Snow Leopard, but I want El Capitan as my main OS.
    2. When in Snow Leopard, I go to system preferences>startup disk and El Capitan does not show up.

    I know about booting the machine while holding option key, but I'd rather use the system prefs to choose my boot OS, especially since I plan to buy a PC graphics card that won't give me a boot screen here soon.

    Thanks
