so I was trying to install Mac OS X 10.3 on my iBook clamshell and the video I saw told me to erase the hard rive so I did but when it asked me what hard rive to put it on I clicked the hardrive and is came up with a warning saying I can't install it to this hardrive because a earlier version is not installed so now when I turn on my Mac it comes up with the flashing finder and question mark symbol if anyone can help me get Mac OS X 10.3 on to my laptop it would really hoelp.
