How to create a BCD backup.

All BCD files are stored in the Boot folder. It is possible to manage them for administration purposes. In addition, they are encrypted to prevent unauthorized changes. Consequently, this action can cause negative effects on Windows startup. On the other hand, Windows has a tool called bcedit. This allows you to create a backup of your boot configuration and restore it when necessary. In addition, BCD boot configuration data is stored in a data file in the Windows registry. Its path is as follows:

HKEY_LOCAL_MACHINE\BCD00000

In the case of UEFI boot, this file will be in /EFI/Microsoft/Boot/BCD on the EFI system partition. Well, now we will use CMD to create a backup of BCD. The first thing you have to do is open a command prompt as an administrator:

Then run the bcdedit command to see the current file structure.

Now we are going to export the contents of this folder to a path. For security reasons, it is convenient to use a different disk or partition than where Windows is installed. So first, please create the folder in the location of your choice.

Then, please use the following syntax:

bcdedit /export “path bcd.bcd”

Please remember to replace path with the address of the folder you will be backing up. In my case, the command looks like this:

bcdedit /export "E:\BCD\bcd.bcd"

You can verify the operation by going to the path:

How to restore a BCD backup in Windows 10

The procedure for restoring a BCD backup is quite simple. Just run the following syntax from a CMD with administrator privileges:

bcdedit /import “path”

In my case:

bcdedit /import "E:\BCD\bcd.bcd"

In this way we have seen how to backup and restore BCD in Windows 10. So if there is a problem with the system startup, we can resort to this backup. Okay, that’s it for now. See you later!

How to create a BCD backup in Windows 10

A very simple way to create a BCD backup is by using Command Prompt. With this in mind, type CMD into the search bar and then launch it with administrator privileges

Then execute the following command:

bcdedit /export E:backup.bcd

Please remember to replace the letter E with the letter of the unit where the backup will be stored. Also, replace backup with the name you want to assign to the file. Additionally, remember to save the file on a secure drive that you can access in case of a system error.

After pressing Enter, a copy of the BCD will be saved in the selected unit. This way, you can restore it in case of system error.

How to back up BCD using third-party tools

If you don’t feel comfortable using the command line, then you can resort to third party programs. In this case, we will use EasyBCD. This free program allows you to manage the bootloader of your computer. But it is also possible to make backup copies of the BCD. Once downloaded and installed, just click on BCD Backup/Repair. Additionally, the menu is very intuitive since it allows you to manage the backup destination and the file name. On the other hand, the tool also provides the function to restore BCD backups.

How to repair the BCD if I don’t have a backup

Imagine this scenario: You turn on the computer and the system won’t start. Most likely you have a bad BCD. And if you don’t have a backup, the situation is worse. In that case, just use the tools provided by Windows to repair the corrupted boot file. As a requirement, you must start the system with the Windows 10 boot disk. But instead of installing the system, click on Repair your computer.

Then select Troubleshoot

Now click on Command Prompt.

Once inside the CMD, you must execute the following commands:

bootrec /fixmbr: Writes a new MBR

bootrec /fixboot: Writes a new boot sector to the system partition, fixing possible damaged sectors

bootrec /rebuildbcd: Scans all hard drives connected to the computer. Also, if it detects Windows installations on any of them, it adds it to the BCD.

Finally, exit the CMD and reboot the computer. If everything has gone well, then the system will boot normally as the BCD will be restored.
