Recovery information
This section provides information about recovery solutions. There are various methods to choose from when
considering how to recover in the event of a software- or hardware-related problem. Recovery methods vary
depending on the type of operating system that is installed. Ensure that you follow the correct recovery
procedures.
Restoring the factory contents with the Recovery Disc Set for the
Windows 7 operating system
When the main storage drive is replaced because of a failure, no product recovery program is on the new
drive. In this case, the customer must use the Recovery Disc Set to recover the computer. Order the
Recovery Disc Set and the drive at the same time so that the customer can restore the computer to the
factory default settings by using the Recovery Disc Set after the new drive is installed. For information about
