If the manual method failed to fix the BCD issue, you have to use the automatic batch file as followings:

§  Download the BCD.zip from this link using your mobile or in another computer.

§  Extract the downloaded file into your mobile

§  Connect a USB drive to your mobile and then copy the extracted folder and everything inside it into the USB.

§  Connect the USB to the PC and open Command Prompt

§  Type DISKPART and press Enter

§  Type LIST VOL and press Enter

§  See if there is any volume without assigned letter and select it using SEL VOL followed by the volume number. For example, to select the volume number 2, type SEL VOL 2 and press Enter.

§  Assign any free letter that is not assigned to another volume using this command:

§  ASSIGN LETTER= followed by the desired letter

§  Repeat previous two steps to assign a free letter to all volumes that don’t have a letter.

§  Press up Arrow key from keyboard to explore and use previous commands

§  Type EXIT and press Enter to leave the DISKPART

§  Type NOTEPAD and press Enter

§  From File tab, select Open option

§  Click on This PC and then locate the USB drive.

§  Open the USB drive and then open BCD folder

§  Change “Files of type” option to “All Files”

§  Right click on Auto-Rebuild-BCD file and then select, Run as Administrator

§  This auto file will format the System or EFI partition and then rebuild the BCD automatically. Also it will create a new partition for the System or EFI if there is no one due to disk cloning or for any reason.

§  If there is a separated system or EFI partition for the BCD in your computer, the auto batch will locate and then format it. After that, it will rebuild the BCD and enable the Recovery Environment. But you will be asked to ad windows installation to the BCD.

§  Type Y or Yes to confirm addition of the identified windows into the BCD data.

§  If you have a dual boot system, Type A or All to add all identified operating systems to the BCD file.

§  If not sure, type Y or Yes to add the identified Windows installation that has :\Windows path only, and ignore the windows that has a Windows.old on its path by typing N or NO and pressing Enter.

§  Once you see the successful message of Reagentc, press any key to close the auto CMD window

§  Close all opened tabs and then click on Continue to restart your system.

NOTES:

§  In older Windows 10 with MBR disk scheme or Legacy firmware, the Boot Configuration Data or BCD file may be stored in the windows partition. In such case, the CMD script will rebuild the BCD without formatting the partition.

§  If you still have a blue screen error after a SUCCESSFUL rebuild using auto batch file, then the problem is not related to the BCD, so you have to identify the new error message and error code to know what is the source of new blue screen boot loop.

§  To avoid errors when using the Auto batch file, make sure you have assigned a free letter to all volumes.
