Troubleshooting Tools 63
Using the Operating System CD
Before You Begin
If you are considering a reinstall of the Windows XP operating system to correct a problem with a newly 
installed driver, first try using Windows XP Device Driver Rollback (see "Using Windows XP Device 
Driver Rollback" on page 58). If Device Driver Rollback does not resolve the problem, then use System 
Restore to return your operating system to the operating state it was in before you installed the new 
device driver (see "Using Microsoft
 
Windows XP System Restore" on page 60).
  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 ResourceCD
  NOTE: The ResourceCD contains drivers that were installed during assembly of the computer. Use the 
ResourceCD to load any required drivers. Depending on the region from where you ordered your computer, or 
whether you requested the CDs, the Drivers and Utilities CD and Operating System CD may not ship with your 
system.
Reinstalling Windows XP
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.
