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 35.
CAUTION: Before performing the
installation, back up all data files on your
hard drive. For conventional hard drive
configurations, the hard drive is the first
drive detected by the computer.
Use Operating System Reinstallation media only
as the last method to restore your operating
system.
To reinstall Windows, you need the following
items:
Operating System • media
Dell • Drivers and Utilities media
NOTE: The Dell Drivers and Utilities media
contains drivers that were installed during
the assembly of the computer. Use the
Dell Drivers and Utilities media to load any
required drivers. Depending on the region
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. Alternatively, you can also
use the Dell Factory Image Restore as it
contains all the drivers that are available
on your computer.
