Using the Operating System CD
Before You Begin
If you are considering reinstalling the Windows operating system to correct a problem with a newly
installed driver, first try using Windows Device Driver Rollback. See "Using Windows Device Driver
Rollback" on page 92. 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 System Restore" on page 95.
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, you need the following items:
•Dell™

the Dell Drivers and Utilities CD to load any required drivers. Depending on the region from where you ordered your
computer, or whether you requested the CDs, the Dell Drivers and Utilities CD and Operating System CD may not
ship with your computer.
Reinstalling Windows
The reinstallation process can take 1 to 2 hours to complete. After you reinstall the operating system, you

support representative instructs you to do so.
