Q: I have two hard drives on my G5(2004). How do I get to choose which hard drive is the start up disk when I turn on the computer? Is it the shift key I hold down?

    Hello,

     

    It's the Option or alt key on bootup that brings up the Startup Manager!

     

    Shift key does a Safe Boot.

    depending on which model of G5 and  OS installed will depend on whether a key command will work

     

    alt   at start up may  work, if it does not, use the start up disc setting in;  

    apple menu > system preferences > system  > start up disc

     

    of course, the second drive must have a compatible OS installed for it to be able to boot.
