Resolving MBR corruption in Windows 7 and performing Windows HDD recovery

MBR or (Master Boot Record) is the first sector of a hard disk which contains the main partition table and the boot loader program.

As this sector is the most critical part of the disk, it is a common target for various viruses and other malicious software. Other reasons for MBR corruption include improper system shutdown, power surge, human errors etc. This halts the booting process of the computer and results in system inaccessibility. To overcome the problem and recover all the lost data, you need to go for hard drive recovery through a reliable hard drive utility.
