Reinstallation
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 Windows Device Driver Rollback. 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 “System Restore” on page 44.
CAUTION: 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.
Restoring Your Operating System
To reinstall Windows, you need the following items:
•Dell Operating System disc
•Dell Drivers and Utilities disc
NOTE: The Dell Drivers and Utilities disc contains drivers that were installed during the assembly of the computer. Use the Dell Drivers and Utilities disc to load any required drivers. Depending on the region from which you ordered your computer, or whether you requested the disc, the Dell Drivers and Utilities disc and Operating System disc may not ship with your computer.
