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 76. 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 78. 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: The Drivers and Utilities media contains drivers that were installed during the assembly of the computer. Use the 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 Drivers and Utilities media and Operating System media may not ship with your computer.
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.
NOTICE: The Drivers and Utilities media provides options for reinstalling Windows Vista. The options can overwrite files and possibly affect programs that are installed on your hard drive. Therefore, do not reinstall Windows Vista unless a Dell technical support representative instructs you to do so. 1 Save and close any open files and exit any open programs. 2 Insert the Operating System disc. 3 Click Exit if the Install Windows message appears. 4 Restart the computer. When the DELL logo appears, press <F12> immediately. NOTE: If you wait too long and the operating system logo appears, continue

to wait until you see the Microsoft Windows desktop; then, shut down your computer and try again.
