6.6 Bootable Configuration (BCD) Editor

Boot Configuration Data store to make a Windows system partition bootable

Boot Configuration Data (BCD) is a database for boot-time configuration data. It is used by Microsoft's Windows Boot Manager and replaces the boot.ini that was used by NTLDR.

It carries a set of entries describing booting options and location of Windows Boot Loader, Windows Resume application and other important programs.

BCD was introduced along with Windows Vista and it is a replacement of older boot.ini format. BCD store is used by Windows Vista, Windows 7, Windows 8, Windows Server 2008, Windows Server 2012 and Windows 10.

Bootable Configuration (BCD) Editor

After the launch Active@ BCD Editor scans all disks in the system and looks for BCD stores which could be more than one if there are disks presented containing boot configuration from another machine. The first BCD store is open and available to edit. Before making changes make sure that you use a correct BCD store. Use Open BCD command to change the current BCD store.

The main screen contains a list of all BCD store entries and their parameters. Out of those parameters only Application device and OS device are intended to be changed, all other data is shown for information only. The main task of BCD Editor is to assign a correct device for each application in BCD store, so Windows would be booted correctly.
