Problems solved by technology

[0004] To sum up, at present, we can only rely on the active partition and adopt a serial method to achieve multiple boots, but there is no ideal way to allow any disk to support random booting of multiple systems. Once an accident occurs in the active partition, the computer will be unusable. The system seriously affects its availability

Embodiment Construction

[0007] In order to implement the present invention, it involves the use of the boot control program and the hidden area management program. In fact, the same program is used to realize the required functions. For the convenience of description, it is called a specific tool. In addition, grldr needs to be modified to allow it to support access to hidden areas. Only after the preparations in this area have been done, can we start making fault-tolerant multi-boot system disks. The boot control program of the fault-tolerant multi-boot system disk is composed of the contents of the main boot sector, reserved sector and hidden area. The normal startup sequence is related to the purpose of the disk, and the user can also control its loading objects through more than one startup menu, so as to realize multi-boot control. For the system disk of a PC or server, the system with active partition is preferred to start. After checking that the partition table is correct, read the contents ...

Abstract

The invention discloses a manufacturing method of a computer system startup disk, and the manufacturing method is suitable for various types of storage equipment provided with disk partition tables. A target disk is partitioned in a conventional mode and provided with an active partition, and besides, any one original or logic partition in the disk is further divided into two or more storage areas which are used independently; the data storage format of one storage area is consistent with the type of the original partition; specific storage formats are used for the rest of the storage areas. By modifying the content of a main sector, the content of a reserved sector and the content of a hidden area, a guide control program and a main menu are added to the disk, each area is configured with a system startup function and a menu corresponding to the corresponding area by means of an existing startup function or grldr and deformation of the grldr of the original active partition, namely, one or more menus capable of being operated by a user are provided, and a system can be started up from any one area. When any one storage area or startup mode is damaged, the guide control program will automatically select bootable system loading, and therefore the user can have the available operating system at any moment.

Description

technical field [0001] A method for making bootable disks with multiple fault-tolerant systems, which can be used for various storage media with disk partition tables, and aims to increase the selection of multiple bootable systems for system disks and mobile storage devices of various computers and control functions. Background technique [0002] There are many factors that affect the normal startup of the computer. In addition to the need for a complete system startup program, it also depends on the integrity of the main boot program, partition table and active partition boot program. Since the birth of a PC, the system disk can only be set with one active partition and one boot method. Once the active partition is damaged or the partition table is abnormal, the computer will be paralyzed, especially in the Internet age and the prevalence of viruses today. The frequency of such failures It is getting higher and higher, thus seriously affecting the utilization rate of comp...
