Using the Operating System Media
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 132). 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 136).
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 Operating System media
• 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 media, the
Dell Drivers and Utilities
dicsc and Operating System media may not ship with your computer.
Reinstalling Windows XP or Windows Vista
The reinstallation process can take 1 to 2 hours to complete. After you
reinstall the operating system, you must also reinstall the device drivers, virus
protection program, and other software.
