1. A distributed system configurable to communicate in a network, the distributed system comprising:
- a plurality of computational devices coupled via the network;
a distributed operating system controlling the plurality of computation devices; and
a storage partition that stores the distributed operating system and a backup copy of the distributed operating system, wherein the distributed system performs;
receiving, by a boot loader, an indication to load the backup copy of the distributed operating system;
loading, by the boot loader, the backup copy of the distributed operating system; and
rebooting the computational device with the loaded backup copy of the distributed operating system.

Abstract
Provided are a method, system, and article of manufacture for system recovery. An operating system and a backup copy of the operating system are both maintained in a partition of a computational device. A boot loader receives an indication to load the backup copy of the operating system. The boot loader loads the backup copy of the operating system. The computational device is rebooted with the loaded backup copy of the operating system.
