Introduction:

Error description: Failed to update BCD file. Please use Windows Installation CD to amend it.

BCD(Boot Configuration Data) file is used to save the boot information and partition parameters for the systems. Partition Assistant will update BCD file after having changed the system partition’s or boot partition’s position, either when the disk ID has been changed after copying and migrating system. You will be given this error code when the process of updating BCD fails.

Solutions:

Situation 1: If the system is able to boot after receiving the error, then you can pay no attention to it. Otherwise you should redo the partition operation by WinPE boot media created by AOMEI Partition Assistant with Make Bootable Media function.

Situation 2: If your system failed to start, you may try to amend BCD with Windows 7/8 installation CD or with a third-party tool like EasyBCD. If you knows the bcdedit command line inside out, you may also try to rebuild BCD file with the command line from Windows 7 System Repair Disc.

If there is still any problem, please feel free to contact our AOMEI Support Team.
