Boot Configuration Data Is Missing in Windows 10

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

  • 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’.

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.
