When the primary OS has a failure, such as system files becoming
corrupted, registry corrupted, or the system hangs during boot, the
system should be run from the secondary OS. To run the system from the
secondary OS:
1. Power down the unit.
2. Connect a monitor, keyboard, and mouse directly to the rear of the
unit.
3. Power on the unit.
4. During boot up, select to use the secondary partition.
Be sure to back up your user data, and then use the Quick Restore DVD
to restore the ser ver to the factory default state as soon as conveniently
possible.
