Technical Field
The invention relates to the technical field of computers, in particular to a method and a device for restoring a system one-key suitable for a computer operating system.
Background
The operating system is booted by a boot program, which is a small program that starts to execute when the system is powered on, initializes hardware devices, prepares a software environment, brings the software and hardware environments of the system to an appropriate state, and finally starts the operating system. In the using process, the operating system can not be started and the equipment can not work normally due to human misoperation, software damage, hardware failure and the like. In order to solve such a serious failure, the operating system and the software application are usually required to be reinstalled, and system failure recovery of some professional devices may also require field operation of a professional, even returning to the factory for maintenance, which is time-consuming, labor-consuming and high in cost.
In order to solve the trouble of reinstalling the system, a one-key restoration method is generally adopted to restore the system to a normal operable state at present. However, in the conventional system key recovery method, a boot loader (bootloader) and an operating system are placed on the same disk, for example, the boot loader is placed in a first partition of the disk, a working system1 is placed in second and third partitions of the disk, a recovery management system2 is placed in fourth and fifth partitions of the disk, and system backup data is placed in a sixth partition of the disk. And the equipment is normally started and enters a working system1, daily service is processed under the working system1, when the working system1 is damaged and cannot be started, a bootstrap program guides the starting of a recovery management system2, a second partition and a third partition of a disk are mounted under the system2, and a previously backed-up system1 file is copied to the corresponding partitions to complete the recovery of the system. However, the existing system one-bond reduction method has the following two technical problems:
