Embodiment Construction

[0015] Such as figure 1 Shown is an operating environment diagram of a preferred embodiment of the hard disk master boot record repairing system of the present invention. The hard disk MBR repair system 10 runs in the computer 1 . The computer 1 includes a baseboard management controller (baseboard management controller, BMC) 11 , a basic input output system (basic input output system, BIOS) 12 and an operating system 13 . The repairing system 10 of the hard disk master boot record is used for repairing the hard disk master boot record (master boot record, MBR) 14 when the hard disk (not shown) is damaged, and the hard disk master boot record 14 is stored in the hard disk 0 cylinder 0 head 1 sector. The master boot record 14 of the hard disk includes an end flag, and the operating system 13 can be started normally only when the value of the end flag is AA55. Described BIOS 12 also comprises a start count mark, and the value of this start count mark represents whether to ope...

Abstract

The invention relates to a repair system for a master boot record of a hard disc. The repair system comprises an examining module for checking a value of a boot counting mark of a BIOS (Basic Input Output System) during a power on self test of a computer; a reading module for reading the master boot record of the hard disc from a corresponding sector of the computer hard disc when the computer is initially booted according to the value of the boot counting mark; a storage module for storing the master boot record of the readable hard disc to a substrate management controller; and an invoking module for invoking the master boot record of the hard disc stored in the substrate management controller when the value of an end mark of the master boot record of the hard disc is not AA55, and recovering the invoked master boot record of the hard disc to the corresponding sector of the hard disc. The invention further provides a repair method for the master boot record of the hard disc. The master boot record of the hard disc can be effectively repaired by the repair system.

Description

technical field [0001] The invention relates to a management system and method for a hard disk master boot record, in particular to a hard disk master boot record repair system and method. Background technique [0002] After the power-on self-test of the computer, the master boot record (MBR) is the first disk location to be read. Sector 1 of track 0 of the hard disk is called MBR, and its size is 512 bytes. It does not belong to any operating system, and it cannot be read by disk operation commands provided by the operating system. When the MBR is corrupted by a virus or something else, there is no way for the computer to get into the operating system. The common practice now is to back up the MBR to external memory and restore it when needed. However, this type of recovery needs to locate the external memory and obtain information from the external memory, which takes a lot of time and is complicated to operate. Contents of the invention [0003] In view of the above,...
