Before You Begin
If you are considering reinstalling the Microsoft Windows operating system to
correct a problem with a newly installed driver, first try using Device Driver
Rollback (see "Using Windows Device Driver Rollback" on page 68 for more
information). If Device Driver Rollback does not resolve the problem, then
use System Restore (see "Restoring Your Operating System" on page 61 for
more information) to return your operating system to the operating state it
was in before you installed the new device driver.
NOTICE:
Before performing the installation, back up all data files on your primary
hard drive. For conventional hard drive configurations, the primary hard drive is the
first drive detected by the computer.
To reinstall Windows XP , you need the following items:
• Dell™ Operating System media
• Dell Drivers and Utilities media
NOTE:
The Drivers and Utilities media contains drivers that were installed during
assembly of the computer. Use the Drivers and Utilities media to load any required
drivers.
