Problems solved by technology

Currently known methods for recovering computer systems generally use LINUX or DOS to restore and load the system, which is inconvenient for users to operate.
[0003] In addition, in the existing method, the backup operating system may also be stored in a CD or floppy disk, and the user restores the operating system through the CD or floppy disk, and these media are easy to lose, resulting in the user being unable to restore the computer system.

Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] As shown in accompanying drawing 2, it is the partition schematic diagram for the computer hard disk in the present invention.

[0028] Divide the system hard disk into HPA partition and ordinary disk partition. HPA (Hidden Protected Area) introduced the concept of "primary protection area" after the ATA-5 protocol was established. It is realized by directly protecting an area at the back of the hard disk with ATA commands. Not only the operating system cannot see this area , Even the motherboard BIOS cannot read the "main protection area" in the protected state. The HPA partition is a system hidden partition, which cannot be accessed by users under the normal operating system (WINDOWS operating system). In the HPA partition, it is divided into the following three parts:

Abstract

The invention provides a computer system recovery method, comprising the steps: 1. Setting the hard disk information of the computer, dividing the hard disk into a common disk partition and a system hidden partition HPA partition, and the HPA partition includes: retaining a system HPA with a backup of the basic operating system Partition, the HPA partition that stores the function of the system rescue software, and the real-mode system located at the first address of the HPA; write the real-mode boot program in the system boot sector of the hard disk track 0, and point the read path to the first address of the HPA partition; 2. Computer Start, and enter the real mode system under the guidance of the real mode boot program; 3. The real mode system loads the backup operating system according to the trigger signal, and starts the system rescue software stored in the functional HPA partition, and the operation stored in the ordinary disk partition The system is replaced with the OS backed up in the HPA partition. The method of the invention is fast and easy to use, and the backup operating system cannot be written, so as to avoid virus infection.

Description

Technical field: [0001] The invention relates to a new computer system recovery method, and in particular to a method for recovering the computer system through a backup operating system when the common operating system is paralyzed due to virus infection or other reasons. technical background: [0002] Among the existing computers, whether it is a notebook or a desktop computer, many of them have the ability to restore the computer system through the backup operating system when the system is infected with a virus. Currently known methods for recovering computer systems generally use LINUX or DOS to recover the loaded system, which is inconvenient for users to operate. [0003] In addition, in the existing method, the backup operating system may also be stored in a CD or floppy disk, and the user restores the operating system through the CD or floppy disk, and these media are easy to lose, so that the user cannot restore the computer system.
