Deleted File Recovery software and Damaged Master Boot Record

MBR is damaged

The Master Boot Record (MBR) will be created when you create the first partition on the hard disk.

It is a very important data structure on the disk. The Master Boot Record contains the Partition Table for the disk and a small amount of executable code for the boot start. The location is always the first sector on the disk.

The first 446 (0x1BE) bytes are the MBR itself, the next 64 bytes are the Partition Table, the last two bytes in the sector are a signature word for the sector and are always 0x55AA.

Here is an MBR which will be used as an example:
