The boot configuration datastore could not be opened

What is BCDE dit?

BCDEdit is a command line tool used to manage boot configuration data (BCD). Contains a store that is used to describe startup applications and their configuration. Regarding its functionality, BCDEdit can be used for a variety of purposes, which include adding start menu potions, modify existing stores and create new ones from scratch.

What is causing the error $ 0027 The boot configuration data store could not be opened $ 0027?

We investigated this particular issue by examining various user reports and the remediation strategies that affected users have used to get to the bottom of this issue.. It turns out that there are a couple of common scenarios in which this particular problem will appear:

• The command prompt does not have administrator access: in most cases where this error is reported, the problem occurs because the command prompt in which you are trying to use the BCDEdit utility does not have administrator access. Of course, if this scenario is applicable, you can solve the problem by opening a command prompt window as administrator.

• The boot mode is different from the partition type: this error can also occur if you are trying to boot from a partition that was originally created with a different partition type. For BCDEdit to work properly, should boot from the same type of partition that the hard drive was created with.

If you are currently having trouble resolving the error $ 0027 The boot configuration data store could not be opened $ 0027, This article will allow you to fix the problem by providing you with a couple of troubleshooting guides that other users in a similar situation have used successfully .

For best results, follow the methods in the order they are presented, since they are ordered by efficiency and severity.

Method 1: open command prompt as administrator

In most cases, this particular issue is due to a privilege issue. Most likely, BCDEdit will be forced to perform an operation that requires elevated privileges (administrator access). This is even more likely if the submessage associated with $ 0027 The boot configuration datastore could not be opened. $ 0027 The mistake is $ 0027 Access is denied $ 0027.

Several users who encountered this exact error message have managed to resolve the problem and complete the BCDEdit operation by opening the command prompt with administrative privileges. Here's how to do it:

1. Press the Windows key + R to open the Run dialog.

2. Then write “cmd” and press Ctrl + Shift + Enter to open an elevated command prompt. Running CMD as administrator

3. When prompted UAC (User account control), click Yes to grant administrative privileges.

If you still encounter the same error message, go to next method.

Method 2: change boot mode

As some affected users have pointed out, when starting the machine, make sure you are booting from the same time as the partition the hard drive was created with so that BCDEdit works as expected. The quickest way to do this is to change the BIOS mode. This procedure is carried out from the BIOS configuration, but it will differ from computer to computer depending on the motherboard manufacturer and the BIOS version that the motherboard has.

Here's a generic guide that should help you get there, regardless of motherboard manufacturer:

1. Start your computer and press the Settings key during the initial startup sequence. Normally, the configuration key is displayed on the initial screen, but in case you don't see it, it's the F keys (F2, F4, F6, F8, etc.) the Supr (for Dell computers) or the Esc key. key .

   press [key] to access settings Note: You can also search online for your computer's specific setup key.

2. Once you get to the BIOS settings, find a Boot tab and change the Boot Mode to the type the partition was originally created in. In this case, it is a legacy BIOS. Change boot mode

3. After changing the startup mode, save current settings and restart computer.

4. Try using the BCDEdit command again and see if you keep getting the error $ 0027 The boot configuration data store could not be opened $ 0027.
