- If you're restoring a Latitude running Windows 8, access Dell Backup and Recovery by pressing and holding the Shift key when selecting Restart from the shutdown options. Choose Troubleshoot, and then Dell Backup and Recovery. When the computer restarts, Click Next, which runs Smart Repair, and then click Next again to choose the backup file you wish to use. Follow the screen prompts to finish the restore. Unlike earlier versions, you will have the option to back up your personal data as part of the restore procedure.
- Use Ctrl-F11 for older operating systems, if the F8 button doesn't open the advanced boot options menu.
Using Factory Recovery Media
When your hard drive fails, the system restore partition may no longer be accessible. Factory recovery media will allow you restore to defaults after reformatting or replacing your hard drive.
Step 1: Insert the recovery disk
Be sure your Latitude is connected to its power supply and not running just on battery. Insert a recovery media disk into the optical drive or a USB recovery key into a USB port.
Step 2: Select the boot options
Power on your computer and press the F12 key several times when the Dell logo appears. Select your backup media location. You may be prompted to press a key to start a CD or DVD boot.
Step 3: Run the recovery app
The Dell backup and recovery application opens. Click Next to proceed to the hard drive diagnostics and click Next when it completes. The application runs Smart Repair. Click Next again when it completes. Smart Repair will attempt an instant restore if no problems are found. If the instant restore is successful, you will be prompted to restart your computer.
Step 4: Perform the factory reset
Select Factory Reset from the Advanced Options screen. The application presents the opportunity to back up data and settings. Click Next to perform a backup or press Skip to proceed without. The restore process starts after either of these options, proceeding to completion before prompting you to restart your Latitude. Finish restoring your computer using Windows when the computer reboots.
Dell uses a recovery partition on the Latitude models' hard drives as a source of data for the restore process. If you have deleted or modified this partition, you may need to use generic instructions for recovering your laptop.
