I currently have Leopard operating sytem. I have a disk to upgrade to Snow Leopard so that I can upgrad to Lion for the icloud move. I just installed My Book for my back up system. Do I unhook the My Book before I put in the installation disc for Snow Leopard? and do I have to uninstall my Leopard first?
