MBR, the acronym stands for Master Boot Record. It is also known as the partition sector, that is the first 512-byte boot sector of a partitioned hard disk. MBR holds the primary partition table of the hard disk and your LINUX system boots only after the BIOS passes the execution of the machine code inside the MBR. Hence, any problem with the MBR directly affects the booting process of the hard disk, making it inaccessible and the situation demands Linux recovery techniques to bring back your valuable data.

The Master Boot Record is not reside in partition of the hard disk, it is there in the main boot boot record, ahead of the first partition. If a hard disk has been partitioned with the MBR partition table scheme, the MBR contains the primary partition entries in its partition table that is all the information required by the OS to boot up. Where, the first sector stores this, the last end sector stores the information about the bootable partition.

In LINUX, the MBR can be accessed through the command 'dd'. This functionality usually helps in taking backup of your data, restoration of the data and erasing the partition table. Hence, the command is very much helpful and give you certain amount of control over these things. However, these processes may sometimes overwrite or corrupt the MBR and to recover your inaccessible data you wonder for a good LINUX MBR recovery software.

These cases are a sure possibility in case of the dual boot systems, however, due to human errors, viruses, power fluctuation or any hardware/software malfunction can lead to MBR corruption.

In case of a MBR damage or corruption, you have to take one of the following alternatives:

Replace the MBR with a Disk Editor. Replace the MBR with the Recovery Console. If the above measures fail, try to copy the MBR from another drive, however it seldom matches to the existing partition scheme of the original MBR.

If all the above measures fail to resolve the MBR corruption issue and you don't have backup of your data, then, LINUX recovery is the only available alternative. These LINUX recovery softwares are powerful enough to recover your data from the drive irrespective of the data loss situation and are dam easy to use.
