When you started up the tour disk, you began with the computer switched off. But it isn't necessary to switch off the computer each time you want to start up from a new disk. Follow these steps to restart the computer with the Apple IIGS System Disk:
1. Insert the Apple IIGS System Disk in your startup Drive, metal end first and label side up.
If you don't remember which disk drive is your startup drive, refer to "Identifying Your Startup Drive" in the previous session.
2. To restart the computer, press Command-Control-Reset.
