before you installed the new device driver. See "Using Microsoft® Windows® System Restore" on page 42.

NOTICE: Before performing the installation, back up all data files on your primary solid-state drive. For conventional solid-state drive configurations, the primary solid-state drive is the first drive detected by the computer.

To reinstall Windows, you need the Dell™ Operating System media and the 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 Dell Operating System media may not ship with your computer.
