Installation overview

CAUTION: This re-imaging guide is designed for system administrators.

Do not attempt to re-image your computer if you are not an administrator or if you are unsure of the procedures. Failure to follow instructions may result in permanent data loss.
NOTE: Information provided in this guide is only applicable to computers with Windows 11 operating system installed.
NOTE: Dell Technologies recommends that you download and install the device drivers from the Dell Drivers & Downloads website. Installing device drivers from a non-Dell website can cause computer performance issues or corrupt operating system files. It can also cause blue screen errors, unexpected shutdowns, or infect your computer with malicious software.

Device drivers must be updated when you reinstall the operating system using a CD, DVD, or USB drive. Device drivers must also be updated when you are facing networking, graphics, sound, or other hardware-related problems. Dell Technologies recommends that you install or update device drivers if you have performed a factory reset of your Dell Technologies computer. Use the Dell Backup and Recovery application or other factory-reset methods. The driver installation ensures that you have the latest device drivers installed on your computer and that the devices function optimally.

Installing or updating device drivers may lead to the following improvements:

• Increases in computer performance
• Patched security risks
• Expanded compatibility
• Fixed device issues
• Support for new features

However, if your computer is operating normally and there are no driver issues or Windows prompted updates, driver updates may be unnecessary. Updating drivers unnecessarily may create new problems.

Review the importance of each driver update on the Dell Drivers & Downloads page before assessing the need to continue with an update.
