Notes:
1. After restoring a hard disk to the original factory contents you might have to
reinstall device drivers for some devices. See “Recovering or installing device
drivers” on page 46.
2. Some computers come with Microsoft Office or Microsoft Works preinstalled. If
you need to recover or reinstall your Microsoft Office or Microsoft Works
applications, you must use the Microsoft Office CD or Microsoft Works CD. These
CDs are provided only with computers that come with Microsoft Office or
Microsoft Works preinstalled.
Solving recovery problems
If you are unable to access the Rescue and Recovery workspace or the Windows
environment, you can:
v Use your rescue media (CD, DVD, or USB hard disk) to gain access to the
Rescue and Recovery workspace. See “Creating and using rescue media” for
details.
v Use a Recovery Repair diskette to repair the Rescue and Recovery workspace or
repair a file needed to enter the Windows environment. See “Creating and using
a Recovery Repair diskette” on page 45 for details.
v If your intent is to restore the contents of the hard disk to its original factory
state, you can use a set of Product Recovery discs. See “Creating and using
product recovery discs” on page 41.
It
is important to create a Recovery Repair diskette, rescue media, and a set of
Product Recovery discs as soon as possible and store them in a safe place as a
precautionary measure.
If you are unable to access the Rescue and Recovery workspace or the Windows
environment from rescue media, a Recovery Repair diskette, or a set of Product
Recovery CDs, you might not have the rescue device, CD drive, DVD drive or USB
hard disk drive defined as a startup device in the BIOS startup sequence. See
“Setting a rescue device in the startup sequence” on page 46 for more information.
Creating and using rescue media
Rescue media such as a CD or USB hard disk drive enables you to recover from
failures that prevent you from gaining access to the Rescue and Recovery
workspace on your hard disk.
Note: The rescue disc, the first disc of the Product Recovery discs and the backup
discs are startable (bootable). They can be started in any type of CD or DVD
drive except for a DVD-RAM media.
