ABSTRACT:
Disclosed is a method for implementing data backup and recovery in a computer hard disk. The method includes the following steps. First, a computer motherboard is powered up and BIOS is booted through triggering of hardware. At the same time, information about a computer bootstrap mode is stored in a recording device, the information representing a mode to start a conventional operating system or a mode to start a backup/recovery function. Then BIOS reads the information about the computer bootstrap mode from the recording device and determines which mode it represents. If the information represents a mode to start a conventional operating system, the computer is booted with a preinstalled conventional operating system. If the information represents a mode to start a backup/recovery function, BIOS operates the protection partition of a hard disk, loads the kernel of an inserted operating system and performs the backup/recovery processing. According to the invention, the data backup/recovery function can be started directly through triggering hardware, and the loaded inserted operating system can be dynamically updated, so it is more convenient and flexible in application.
