Before You Begin
If you are considering reinstalling the Windows XP operating system to correct a problem with a
newly installed driver, first try using Windows XP Device Driver Rollback. If Device Driver
Rollback does not resolve the problem, then use System Restore (see page 40) to return your
operating system to the operating state it was in before you installed the new device driver.
NOTE:
The Drivers and Utilities CD contains drivers that were installed during assembly of the computer.
Use the Drivers and Utilities CD to load any required drivers, including the drivers required if your
computer has a RAID controller.
Reinstalling Windows XP
NOTICE:
You must use Windows XP Service Pack 1 or later when you reinstall Windows XP.
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 CD
• Dell Drivers and Utilities CD
To reinstall Windows XP, perform all the steps in the following sections in the order in which
they are listed.
The reinstallation process can take 1 to 2 hours to complete. After you reinstall the operating
system, you must also reinstall the device drivers, virus protection program, and other software.
NOTICE:
The Operating System CD provides options for reinstalling Windows XP. The options can
overwrite files and possibly affect programs installed on your hard drive. Therefore, do not reinstall
Windows XP unless a Dell technical support representative instructs you to do so.
NOTICE:
To prevent conflicts with Windows XP, disable any virus protection software installed on your
computer before you reinstall Windows XP. See the documentation that came with the software for
instructions.
