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 page146). 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 page156).
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 media
NOTE: Your Drivers and Utilities media contains drivers that were installed during
assembly of the computer. Use your Drivers and Utilities media to load any required
drivers, including the drivers required if your computer has a RAID controller.
Reinstalling 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.
