Abstract
A recovery method for a master boot record of a hard disk drive is adapted to a computer system incorporating extensible firmware interface (EFI). When modification occurs in the master boot record, the extensible firmware interface stores the master boot record in an NVRAM (Non-volatile Random Access Memory) as a backup. The backup is read out for recovery of the hard disk driver if the master boot record is destroyed. The NVRAM is write-protected during runtime and the backup data stored therein is therefore free from destruction.
