Abstract:
1. An electronic apparatus, comprising: a storage unit to store a first (primary) GPT, a second (secondary) GPT, and an OS; a controller to boot the electronic apparatus using the first GPT and the OS; an effectiveness determination unit to determine effectiveness of the first GPT if a predetermined event occurs; and a restoration unit to restore the first GPT using the second GPT if the first GPT is not effective, wherein: if the electronic apparatus is booted, the controller generates backup data for the first GPT and stores the backup data in the storage unit; if the first GPT is not effective, the effectiveness determination unit determines whether an entry of the first GPT is identical to an entry of the backup data; and if the entry of the first GPT is identical to the entry of the backup data, the restoration unit restores a header of the first GPT using a header of the backup data.
