Abstract
A method, a device, and a non-transitory storage medium provide to store a boot loader that includes a first stage boot loader and a second stage boot loader, and wherein the first stage boot loader is not upgradeable and the second stage boot loader is upgradeable; store a first operating system and a second operating system, wherein the first operating system is a main operating system and the second operating system is an operating system that is executed only when a disaster recovery service is invoked; execute the first stage boot loader during a boot-up of the device; determine whether the disaster recovery service is invoked during the execution of the first stage boot loader; load the second stage boot loader in response to a determination that the disaster recovery service is invoked; and determine whether an upgraded second stage boot loader is stored at the device in response to a determination that the disaster recovery service is not invoked.
