What is the first step you should take before re-imaging a computer?

Before re-imaging a computer, the first step is to back up data. This step is crucial because re-imaging a device typically involves wiping the existing operating system and all programs, which results in the loss of any stored user data. Backing up ensures that all important files, documents, and settings are saved and can be restored after the re-imaging process is completed.

This precaution protects against accidental data loss, which could lead to significant issues for users who rely on specific information or personalized configurations for their work or personal tasks. After backing up the data, you can safely proceed with the re-imaging process, knowing that any critical information is secured.
