Probably you have got the message on your computer screen- ‘The boot configuration data for your pc is missing or contains errors. To run the computer simultaneously, you need to work with the issue as soon as possible. But, do you not understand how to deal with the message?

Welcome, you have come to the right place. I will discuss the fixes in the entire article. The discussion will be held based on Windows 10 operating system.

How to Fix ‘the Boot Configuration Data for Your PC Is Missing or Contains Errors’ Issue

Boot Configuration Data (BCD) is an operating-system-related database. BCD missing can occur for many reasons like unexpected shutdown, extended system active partition, or even hardware failure.

There are some ways to fix the issue. Before diving into the details, let have a look first at the glimpse of all possible fixes –

• Automatic Repair
• Rebuild BCD
• Create BCD
• Set Windows Partition Active

Automatic Repair

You may choose the automatic repairing option before applying the manual options. To do that, you have to follow the step-by-step process. Hopefully, the issue will fix.

Step 1

Firstly, you need to manage a bootable drive or disk. Yes, CD/DVD is rarely used nowadays. So, you can use any bootable Pendrive instead of CD/DVD. You have to insert the drive or disk and press the power button or restart your computer.

Step 2

While starting the computer, you must have to press a single key to enter the boot menu. Key may vary depending on computer manufacturers. In common cases, it can be ‘exc’, ‘f2’, ‘f10’, or ‘f12’.

From the boot menu, you need to go to the Windows setup interface. Here, you have to select a language and click on ‘Next’.

Step 3

In this stage, you will find the ‘Repair Your Computer‘ section at the left bottom of the interface. You would enter inside the section with a click.

Step 4

There will be the ‘Troubleshoot‘ portion inside the ‘Repair Your Computer‘. You have to go inside it.

Step 5

Here you will find the ‘Advanced options‘. You have to work with the section.

Step 6

Here, you will see the ‘Automatic Repair‘ option. After clicking on it, the process will complete automatically. You have to restart the computer to check whether the issue is solved or not.

If the computer still shows the message, you need to apply the next fix.

Rebuild BCD ( Boot Configuration Data )

Rebuild BCD is the first manual action to fix the BCD missing issue. Let do it by following a couple of steps. 

Step 1

Here, you have to work with ‘Command Prompt‘. It is commonly known as ‘cmd’. You will get it in the ‘Advanced options ‘.  

Again, you have to follow the same sequence described in the previous fix- Windows Setup Interface> ‘Repair your computer’ > ‘Troubleshoot’ > ‘Advanced options’> ‘Command Prompt’

Step 2

Then you need to type the following command one by one in the ‘cmd’. Here you have to press ‘enter’ each time after typing one.

‘bootrec.exe /rebuildbcd’

‘bootrec.exe /fixmbr’

‘bootrec.exe /fixboot’

Finally, you will get a message- ‘The operation completed successfully.’ If you do not get it by any chance, you must follow the next step to fix the issue.

Step 3

In this step, you need to type the following command in the cmd like the previous step and press enter after typing the commands each time.   

‘bcdedit /export c:\bcd_backup’

‘c:’

‘cd boot’

‘attrib bcd -s -h -r’

‘ren c:\boot\bcd bcd.old’

‘bootrec /rebuildbcd’

Step 4

To maintain the sequence, you should type ‘exit’ after getting the message- ‘The operation completed successfully.’ Then press ‘enter’. Finally, you have to restart your computer.

If your computer still shows the BCD missing notification, you would follow the next solution.

Create BCD ( Boot Configuration Data )

Creating BCD can be a perfect solution to fix the BCD missing issue. You have to follow the steps described below.

Step 1

You have to work again with the ‘Command Prompt’. To get access to the command prompt, you would follow the sequences chronologically- Windows Setup Interface> ‘Repair your computer’ > ‘Troubleshoot’ > ‘Advanced options’> ‘Command Prompt’

Step 2

Then you have to type ‘bcdboot c:/windows’ in the command prompt and press enter. As a result, the BCD file will be copied from the windows partition and bring it to the motherboard partition. 

By conducting the process, Boot Configuration Data will create. Now, your task would restart the computer again.

Hopefully, the problem might solve. But if it does not solve yet, you need to apply the next fix.

Set Windows Partition Active

The Windows partition of your computer might not be active. It is another reason for BCD missing. You can set the Windows partition active by following some steps.

Step 1

Here you also need to type some commands in cmd. Follow the sequence again to get access of the cmd- Windows Setup Interface> ‘Repair your computer’ > ‘Troubleshoot’ > ‘Command Prompt’

Step 2

In this step, you have to type the following command and press ‘enter’ each time.

‘diskpart’

‘list disk’

‘sel disk 0’

‘list partition’

‘sel partition 1’

‘active’

‘exit’

Here, your task would restart the computer and take a final check.

Final Words

In the end, I would especially remember you that- try to be careful when you are typing commands in the cmd. Even, you should not miss a space. If you type something in the wrong format, the process will not work and your computer shows the message again- ‘The boot configuration data for your pc is missing or contains errors.
