To install or remove system software on a hard disk, or to initialize a hard disk, you need to start up your computer from a CD-ROM disc that contains system software, such as your software install or software restore CD.
Starting Up From a CD
When starting up from a CD, make sure you use a CD that contains system software.
- Turn on your computer if it's not already on.
- Press the CD Eject button on the front of the CD drive to open the tray.
- Place the CD in the tray with the disc label facing up.
Make sure the disc is lying flat in the tray.
- Gently push the tray in to close it.
- Make sure the Caps Lock key is not engaged.
- Hold down the C key on your keyboard while you choose Restart from the Special menu.
- When you see the screen that says "Mac OS" and the phrase "Starting Up," release the C key.
In a few seconds the desktop appears. The CD icon appears at the top-right corner of the desktop (above your hard disk icon), and the Apple menu does not contain the usual items.
Note: The desktop pattern will be different from the pattern you normally see, since your computer is now using the system software that's on the CD. Your regular desktop pattern will reappear when you start up from your normal startup disk.
If the above procedure doesn't work, make sure the CD is inserted properly, restart the computer, and hold down the Command, Option, Shift, and Delete keys (to temporarily disable the hard disk). Hold the keys down until you see the screen that says "Mac OS" and the phrase "Welcome to Mac OS."
