BIOS (Basic Input Output System, Basic Input or Output System (BIOS)) has initiating hardware, detection hardware, and the function of guiding operating system.Bios program is deposited among the ROM (Read Only Memory, ROM (read-only memory)) that content can not be lost after the power down, and the address of article one instruction of processor can be positioned among this ROM during system power-up, so that bios program obtains carrying out.BIOS belongs to software program, but because it is the program that is solidificated in the hardware ROM (read-only memory), so also be known as firmware (Firmware).
Along with extensively popularizing of computer technology and technique of internet used, produced the data of magnanimity, wherein major part is stored in the hard disk.Traditional MBR (Master Boot Record, Main Boot Record) hard disk, max cap. are 2TB (TeraBytes, terabyte), and each disk has at most 4 main partitions, perhaps comprises 3 main partitions, 1 extended partition and unconfined logical drive.What substitute gradually at present the MBR hard disk is GPT (Globally Unique Identifier Partition Table, global unique identification partition table) hard disk.GPT is a kind of new disk partition framework, and max cap. can reach 18EB (ExaBytes, Chinese mugwort byte), and each disk has at most 4,300,000,000 subregions.Obviously different from the MBR hard disk is that vital platform operations data are positioned at subregion, rather than are positioned at case of non-partitioned or hiding sector.In addition, the GPT Multi-zone disk also is provided with main partition table (Primary GPT) and backs up the integrality that partition table (Backup GPT) improves partitioned data organization.
Beginning and latter end at the GPT hard disk are being stored the key messages such as GPT head and partition table.Because the destruction of virus, the error of operation and many accidental factors may make GPT head and partition table be destroyed, thereby can't normal load operating system, even damage boot sector, cause the loss of data in the hard disk.
There are at present two kinds of startup restoration methods can solve the problem of booting operating system failure, first method is at DOS (Disk Operating System, disc operating system (DOS)) backs up first the information such as GPT head and partition table under, then when BIOS guiding operating system goes wrong, the information of backup is loaded into the fault sector finishes the startup recovery.Second method is to carry out the backup of subregion backup or DISK to Image with data backup software Symantec Ghost, then starts under the DOS interface and recovers.
But first method is to carry out hard disk backup at the DOS state, occurs easily wrong or failure.Second method backup subregion or DISK to Image need the long time, and release time is also longer, and backup need to take very large storage space, and the waste resource is only supported traditional MBR hard disk at present, does not support the GPT hard disk; If the content in the hard disk is changed, then need again to back up, to waste time and energy, complicated operation is difficult for grasping.
