The boot configuration data store (BCD) contains boot configuration parameters and controls how the operating system is booted for Windows Vista and later versions. Unlike Boot.ini in XP, BCD stores data in a binary format and cannot be edited with a text editor.
Visual BCD Editor is a free tool for Vista and Windows 7 operating systems, and provides a graphical user interface for command line utility BCDEdit. Once installed, it provides two main features: Startup Repair and Visual BCD Editor.
The Startup Repair feature can be used to repair BCD, repair bootsector and MBR (Master Boot Record), and repair disk as well.
