The following sections describe how to use the System Recovery and
Application Recovery utilities.
You can reinstall software titles that shipped with your computer if they
are corrupted or accidentally erased. You may not need to recover the
entire contents of your hard drive. If you experience a problem with your
computer, reinstalling an individual device driver or software title may
correct the problem. Use the Application Recovery CD(s) to reinstall
individual applications or device drivers. See "Using the Application
Recovery CD(s)" on page 101.
The System Recovery CD contains a backup copy of all the software
originally installed on your hard disk drive. It can be used only to
recover the hard disk of the notebook you purchased.
The System Recovery utility gives you three options:
Full Restore without Format restores all the software titles that
originally came with your computer without formatting the hard
disk.
Full Restore with Format formats the hard disk drive and then
restores all the original software.
Operating System Only restores the Windows® operating system,
the notebook utility programs, and the device drivers that shipped
with your computer.
