What should a user do to preserve BIOS settings before starting the recovery process?

To preserve BIOS settings before starting the recovery process, the user should set the "Reset NVRAM" option to "Disabled." This prevents the system from resetting the Non-Volatile Random Access Memory (NVRAM) where BIOS settings are stored. When NVRAM is reset, it can clear important configurations and custom settings, such as system time, boot sequence, and hardware configurations.

By keeping the "Reset NVRAM" option disabled, the user ensures that those settings remain intact during the recovery process. This is crucial as it allows the system to boot using the previously configured settings, which could be essential for the recovery operation to proceed smoothly without having to reconfigure BIOS options afterward.
