Operating System Reinstallation
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. 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 33.
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.

Dell Operating System • media
Dell Drivers and Utilities • media

from which you ordered your computer, or
whether you requested the media, the Dell
Drivers and Utilities media and Operating
System media may not ship with your
computer.
