If anyone of the above symptoms shows up on your PC, don't worry. If you receive the following error messages while booting up PC, it means that the MBR is corrupted on your PC:

What happens if MBR is corrupted? Corrupted or damaged MBR will stop you from entering the operating system, showing error messages like the operating system not found, or simply a black screen without any prompt message. Mostly, MBR corrupted or damaged error is caused by improper unplugging, sudden power failure, virus infection, etc. The MBR partition contains two important components:īoth two components work together to transfers program control to the boot sector of that partition so as to continue the boot process and help Windows OS boot up successfully. It's the first 512 bytes of your hard disk as the image shown here.

The Master boot record is created by the MBR generator when you first install Windows on an MBR disk. The MBR, short for Master Boot Record, also known as the 'master partition table' or 'partition sector', is a boot sector (a region of your hard drive) that holds information about the partitions of your hard drive and acts as a loader for the operating system you're running.

Right-lick the OS disk and choose 'Rebuild MBR'.
