Windows systems or laptops use a boot configuration data file (BCD) to set the boot configuration. If the system or laptop’s boot configuration data file is corrupt or missing due to an internal or external problem, Windows will not boot.
Fortunately, there are several solutions to help you get rid of the “Missing BCD File” error on your Windows 10 computer. And in this article, I will list all these solutions.
So, go through these solutions one by one and fix this problem in a few clicks.
What is the cause of the “Missing boot configuration data file” message?
You need to know what boot data is and what the causes and dynamics of this error are. Boot configuration data is a database used to boot the operating system. There are different boot modes in which the BCD is located differently, e.g. for UEFI the BCD is located in /EFI/Microsoft/Boot/BCD and for EFI system partitions it is in /boot/BCD on the active partition. If there is a problem with this BCD file, this type of error can occur. This error can have several causes: hardware failure, unexpected shutdown, extended active system partition.

If the partition on which Windows is installed is not active, Windows may fail to boot and give an error message "The boot configuration file does not contain certain required information". Simply make the Windows partition active and the problem will be solved.
The BCD information is in the bootmgfw.efi data file in the EFI section of the \EFI\Microsoft\Boot folder.
Boot Configuration Data (BCD) is a firmware-independent database for boot configuration data. It is used by the new Microsoft Windows Boot Manager and replaces boot.ini used by NTLDR. In the case of UEFI boot, the file is located in the /EFI/Microsoft/Boot/BCD directory on the EFI system partition.
