Solved: The Boot Configuration Data Store Could Not Be Opened

User Case

Some Windows users have reported the "Boot configuration data store could not be opened" error when trying to run the BCDEdit command in Command Prompt. Most of the time, this error is accompanied by a sub-error such as "Access is denied" or "The requested system device cannot be found". This issue is not unique to a particular Windows version, as it is confirmed to occur on Windows 7, Windows 8 / 8.1 and Windows 10, 11.

What Is BCD and BCDEdit?

Boot Configuration Data (BCD) store is an important Windows component where Windows boot options are stored based on the BIOS or UEFI boot mode of the computer. It provides a command-independent, firmware-independent boot options interface. You can manage the BCD and boot options with administrator-assigned privileges.

BCDEdit is a command line tool for managing Boot Configuration Data (BCD). It contains a store for describing boot applications and boot application settings. Speaking of its capabilities, BCDEdit can be used for a variety of purposes, including adding boot menu potions, modifying existing stores, and creating new stores from scratch.

What Causes the Error that the Boot Configuration Data Store Could Not Be Opened?

After analyzing a large number of user reports and posts, we found that the boot configuration data store could not be opened error often occurs when they improperly clone a disk using a third-party tool and then run the BCDEdit repair command. We found that the error is mainly related to the following reasons.

🔮 Command Prompt window do not have administrator privileges. Managing the BCD requires administrator privileges to access it. You may encounter this error if you are not running the BCDEdit repair command as an administrator.
🔮 Lost or corrupted Boot Configuration Data file: This is the boot cause of the boot configuration data store could not be opened error. You can try to rebuild the BCD to solve this problem.
🔮 The boot mode is not the same as the partition table of your disk. If the boot partition type is set to a different boot mode than the current one, the BCDEdit repair tool does not work properly and elicits the error that the boot configuration datastore could not be opened in Windows 11/10.

Solution 1. Run Command Prompt as Administrator

In most cases, this particular problem occurs due to a permissions issue. This is more likely if the sub-message associated with the "Boot configuration data store could not be opened" error is "Access is denied". You need to access Command Prompt as administrator.

✨ Note: If your computer is not booting properly due to an error, you can first go to Advanced Boot Options (WinRE) and then run a Command Prompt from WinRE.

1. Type cmd in the Windows search box, then right-click on the Command Prompt application from the top results and select Run as Administrator.

2. When you’re prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
3. Once you’re inside the elevated Command Prompt, perform the same operation that was previously triggering the ‘Boot configuration data store could not be opened’ error and see it has been resolved.

Solution 2. Change the Boot Mode

As mentioned above, you need to make sure that the partition you are booting from is the same type of boot mode (BIOS or UEFI). If it is not, the error "The boot configuration data store could not be opened, the requested system device cannot be found" will appear. In this case, you can try to change the boot mode to suit your partition type.

1. Start your computer and then hold down the F2 and Delete buttons before your computer boots. You will then enter the BIOS.

✨ Note: BIOS hotkeys may vary from PC manufacturer to PC manufacturer. Most modern motherboards use the Delete or F2 key. Usually, you can see a message on the Windows boot screen telling you which key to press to enter the BIOS.

2. Use the left or right click to navigate to the Boot tab and change the Boot Mode to the type set for your boot partition. If the partition table is set to MBR, you should select Legacy BIOS. If the partition is set to GPT, then select UEFI boot mode.

3. Once the boot mode has been changed, save the current configuration and restart the computer.

Solution 3. Rebuild BCD

If none of the above methods can fix the "The boot configuration data store could not be opened" error, you can consider rebuilding the BCD manually in WinRE. To do so, you need to use the Windows 10 Media Creation Tool.

1. Insert the installation media into your computer and boot from the media.
2. After booting, click Next -> Repair Your Computer -> Troubleshoot -> Command Prompt in order.

3. In the Command Prompt window, type the following commands in order and click Enter after each command.

• bootrec /fixmbr
• bootrec /fixboot
• bootrec /scanos
• bootrec /rebuildbcd
