MBR (Master Boot Record) is the most vital disk component, created at the time of disk partitioning. It further comprises master boot code (the executable code), disk partition table, and disk signature, which all together are responsible for error-free data access. Any hard disk, partitioned with MBR scheme can become unbootable under Windows if its MBR gets corrupt. Since it contains the first code executed by computer, MBR is the most frequently targeted component of virus writers. However, to recover from data loss problems, best solutions are Windows repair utilities, backup, and Hard Drive Data Recovery software.

To elaborate such possible events further, let's take a suitable example. Consider a using that tries to download and install a game from Internet to its Windows based computer. When doing so, it receives an error that reads as below:

“Error writing to disk”

Further, it encounters a complete hard drive crash and computer becomes unbootable. Whenever, he/she attempts to start the Windows computer, it gives an error message, mentioned underneath:

“Hard disk read failure: No bootable devices - Strike F1 to Retry boot, F2 for setup utility.”

Consequently, no data is accessible to the user.

Cause

The above symptoms indicate the presence of a fatal virus in game application that has corrupted the hard drive MBR.

A computer cannot boot with a corrupted or missing MBR.

Solution

Following is the solution to recover from such problems:

Insert the Windows installation CD to boot your computer Press 'R' to start Windows Recovery Console Select the Windows installation, you want to repair Access its command prompt and run 'fixmbr' command to replace the damaged MBR

If this doesn't resolve the existing issue and a backup is available, you can reformat the hard drive and reinstall Windows or otherwise, you need to use a Hard Drive Recovery utility. The Hard Drive Data Recovery tools can scan and restore lost, inaccessible, or deleted data from all types of logically crashed hard drives by running effective algorithms.The Hard Drive Recovery tools can scan and restore lost, inaccessible, or deleted data from all types of logically crashed hard drives by running effective algorithms.The Hard Drive Data Recovery tools can scan and restore lost, inaccessible, or deleted data from all types of logically crashed hard drives by running effective algorithms.
