I installed a new (second) harddrive and Leopard this afternoon on my Mac Pro. I still have Tiger 10.4.11 on my "MACINTOSH HD". I partitioned and labeled my new drive "Leopard" (the first partition). The install seemed to go fine to the Leopard volume (it took long, but it worked). Once installed, I did the Software Update thing, and lots more updates were done. It rebooted once or twice to Leopard during the process. I also installed the developer tools. When it rebooted after the Software Update, Tiger came up. I went into System Preferences and picked the StartUp disk to be my Leopard volume. I clicked restart, and Tiger came up. I did this twice, and both times Tiger has come up. How do I set my default boot volume?
