- There are various reasons for computer's being unable to start. MBR damage is a common one. Most computer users know little about hard disk. In the past, actually, Rebuild MBR is privilege of professional staffs who have profound hard disk knowledge. How could common users rebuild MBR?
What is MBR?
MBR is located in the first sector of physical hard disk. This sector is called Master Boot Sector (MBR Sector). The 512 Bytes MBR sector includes 446 Bytes system boot program, and 64 Bytes Disk Partition Table, and ends with "55AA" sign. Generally we can rebuild MBR with WinHex. WinHex is an advanced 16 hex editor special for computer forensic, data recovery, low level data processing, IT security, and other daily emergencies. Professional disk servicemen are using WinHex to restore disk. This picture shows entire 512 Bytes MBR. The blue zone is the 64 Bytes disk partition table, including 4 partition tables. Every partition table is 16 Bytes and includes partition master sign, system sign, start and end cylinder number, sector number, head number, number of front sectors and number of this partition sectors.
MBR damage usually is because of errors in Disk Partition Table which make boot program unable to find system partition. With familiar operations, we can use WinHex to rebuild MBR easily. Analyze the 16 Bytes in the first partition table: 80 01 01 00 0C FE FF FF 3F 00 00 00 41 29 54 02. The first 80 is the activate sign of partition, which means system is able to boot. If it is 0, it means inactive partition. The second 01 means head number. The third 01 means the start sector number. The fourth 00, means start cylinder number. Through analysis, we can master all information about partition. However, this way is too difficult for common users. Using MiniTool Partition Wizard that has graphical interfaces to rebuild MBR is a much simpler and faster way.
