Repair of Windows® 7 BCD
What are the issues that need to be resolved when using Windows 7 BCD?
In Windows 7, boot time configuration data is contained in the 'Boot Configuration Data' store. The BCD is a replacement for the 'boot.ini' file used on Windows operating system earlier than Windows 7 and is a firmware independent file. The Windows 7 operating system loses its booting ability once the 'boot.ini' file gets corrupted. You may edit this file with the help of a command-line tool called 'bcdedit.exe'. The users may use the 'bcd.exe' file to overcome the Windows boot issues. The command line tool does not work if the corruption is high. The solution is to restore from a backup and/or reinstall Windows. You need Windows data recovery solution to recover the lost data when backup is unavailable. Sometimes, your system, loaded with Windows 7 operating system, fails to boot and prompts some error messages. You may not be able access the data stored in the hard drive after receiving the error messages. This is because the boot information in the Windows 7 BCD may be corrupted.

Boot configuration data is used on Windows 7 instead of the 'boot.ini' system file, which was found in the earlier versions of Windows operating systems. The boot environment of the Windows 7 operating system is completely rearranged by Microsoft to address the increasing complexity and diversity of modern hardware and firmware. The reengineering of the boot environment results in a new firmware-independent data store that contains configuration data.
Issues with BCD
Whenever you try to boot your system you may encounter some error messages. The boot process may be halted by the appearance of the error messages. It occurs when you try to boot your system from Windows hard drive. You can access the hard drive partition only if you identify the cause of this behavior using the appropriate tools. The BCD error may occur if 'Bootmgr' entry is not present in BCD. The missing or damaged BootBCD system file on active Windows hard drive partition may also cause BCD error.
Start your system by inserting Windows 7 installation disk inside the drive. If you are prompted to specify language then press any key. Click on the option ‘Repair your computer’ when you are prompted to do so. Then select the target operating system and then click on ‘Next’. You need to choose ‘Command prompt’ under ‘System recovery’ options. Type ‘Bootrec.exe' and then press ‘Enter’. You can repair the BCD using the '/RebuildBcd' option when the tool starts.
