Restoring Your Operating System
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 42.
NOTE: 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
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.
