Ebr Corruption Can Cause Data Loss On Extended Partition

The hard drive in Microsoft Windows , can be divided into several partitions

. There are two types of partitions- Primary and Extended. You can install operating system on any of these partitions. In some situations, you might encounter several problems if you install Windows operating system on an extended partition in dual-boot environment, your system may not boot up and give you some errors. You encounter data inaccessibility and data loss problems. In order to overcome such issue, Windows Data Recovery is required.

As an example, when you boot your Windows system that is configured as dual-boot and in which the operating system is installed on extended partition, you come across following error message:

"OS Loader 4.0 Boot record Signature AA55 Not Found, xxyy Found. Windows NT could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Please check the Windows NT Documentation about hardware disk Configuration and your hardware reference manuals for additional information.

The above error message renders your Windows computer unbootable and critical data inaccessible. In these circumstances, you are required to find out the cause of this problem and then go for Windows Data Recovery to retrieve all of the lost data.

Cause

This problem generally occurs due to corruption the the EBR. The EBR (Extended Boot Record) or EPBR (Extended Partition Boot Record) is the descriptor for logical partitions under general DOS partitioning system. The real structure of extended partition is mentioned by many EBRs that are located in extended partition. The first EBR would always be stored on first sector of extended hard drive partition.

Explanation

The EBR has same structure as of MBR. It is responsible for managing the files on particular hard drive partition and ensure easy and smooth accessing of files. In case of corruption to this data structure, files from the hard drive can not be accessed and data loss situations occur that require Windows Recovery to retrieve data.

The Windows Data Recovery can easily be performed using third party applications, known as Windows Data Recovery Software. The tools use high-end scanning mechanisms for in-depth scanning of Windows hard drive and absolute recovery. They are completely safe and easy to use with rich graphical user interface and read-only conduct.
