Previously, AWS Elastic Disaster Recovery (DRS) restored Linux source servers configured with UEFI firmware in legacy BIOS mode, requiring extra adjustments after recovery. The updated service now preserves the original UEFI boot mode automatically during recovery, eliminating manual reconfiguration steps. This fidelity ensures that applications reliant on specific boot behaviors resume seamlessly.

This feature is available across all AWS Regions offering DRS and is provided at no additional cost. By matching the source environment's boot mode, recovery instances behave identically to their originals, enhancing operational continuity and simplifying disaster recovery workflows.
