If you add a mirror to a boot disk in Windows Server 2003 and use the Computer Management dialog to remove it, switching the boot disk and the mirror disk causes your computer to fail to start.

This behavior occurs because the boot disk information was removed from the Boot.ini file on both the boot disk and the mirror disk when you removed the mirror.

You could have prevented this problem using the following procedure:

1. Disconnect the mirror disk from the computer.

2. Remove the mirror from the boot disk using the Computer Management dialog.

3. Switch the boot disk and the mirror disk.

4. Start Windows Server 2003.

1. If necessary, configure your BIOS to allow starting from a CD-ROM drive.

2. Insert the Windows Server 2003 CD into the CD-ROM drive and restart the server.

3. Press the space bar when you receive Press any key to boot from CD.
