The present invention provides a method for restoring a computer operation system comprising at least steps of: a) backing up information related to start up of the computer in an HPA of a hard disk; b) providing a self-checking module in the HPA of the hard disk, and additionally configuring a command for invoking the self-checking module in BIOS of the computer; c) invoking the self-checking module by the BIOS when the computer is booted from the hard disk, and determining by the self-checking module, whether the information related to start up of the computer is destroyed or not, if so, restoring the destroyed parts and then starting up the computer, and if not, directly starting up the computer. With the present invention, each time the computer is booted from the hard disk, the system will automatically check OS boot program files, hard disk boot information, partition table information and data information in a boot sector of a boot partition, and restore those destroyed parts without users' intervention, and thus it facilitates users' utilizations. Meanwhile, the backed up data are stored with the HPA, and the security of the backed up data is ensured.

Method for restoring computer operating system

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.
