Windows 7 Boot Configuration Data (BCD) store is a database that contains boot-time configuration data. This is a firmware-independent file and is a replacement of boot.ini file used in Windows operating systems earlier to Windows Vista. Once the file get corrupted, a Windows 7 computer loses the ability to boot. Since the file is editable through command-line tool called bcdedit.exe, you can use it to overcome the Windows boot issues. But if the corruption is high or the tool doesn't work, the last alternative is to restore from a backup and/or reinstall Windows. However, while backup is unavailable, you need a Windows Data Recovery solution to recover the lost data.



Consider a practical instance of such problems. You use a Windows 7 based computer and it fails to boot prompting an error that is similar to below:

After this error message, you cannot access the data that is stored on the hard drive.
