Repair BCD Values When BitLocker Fails After Windows 11 Imaging

A resolution is included in this article, along with an explanation of the root cause and steps to remediate the issue.layout.

Issue Description

After deploying a Windows 11 image to devices, attempts to enable BitLocker fail with the following error:

"The path specified in the Boot Configuration Data (BCD) for a BitLocker Drive Encryption integrity-protected application is incorrect. Please verify and correct your BCD settings and try again."

ThisThe problemissue was observed acrosson multiple devices imaged with a FileWave-managed deployment, suggesting a systemic issue withafter the same FileWave imaging orworkflow. Confirm the current BCD configurationvalues process.on an affected test device before treating this as the cause.

Initial Troubleshooting Attempts

Unattend File Adjustments

One of the first suspected causes was the Windows unattend.xml file used during deployment. Specifically, we considered that the partitioning and wiping directives in the answer file conflicted with FileWave’s imaging and partitioning steps.

To test this theory:

  • Removed the entire partitioning section from the unattend file.

  • Re-imaged devices using the updated unattend configuration.

Result: This change did not resolve the BitLocker error.

Manual BCD Edits

We experimented with manual edits to the BCD store using bcdedit, in an attempt to update or repair paths that might be misconfigured post-image. However, these attempts did not lead to a consistent fix.

Resolution

AThe workingtested solutionworkaround wasbelow identifiedcame viafrom a community-sourcedcommunity threadreport on Reddit (source). and was then validated on multiple affected devices.

The issue appears to be related to incorrect device and osdevice settings within the BCD store. BitLocker can initialize successfully by explicitly setting these values to point to the system partition.

Required Commands

ExecuteCheck the followingpartition mapping first. BCDEdit changes can make Windows unbootable. Run bcdedit /enum from an elevated Command Prompt and verify that Windows is on C: and memory diagnostics uses \Device\HarddiskVolume1 before applying this example. Pilot the change on representative hardware before wider deployment.

Run these commands in an elevated Command Prompt: only after the values match:

bcdedit -/set {current} osdevice partition=C:
bcdedit -/set {current} device partition=C:
bcdedit -/set {memdiag} device partition=\Device\HarddiskVolume1

Optional: Batch File Version

You may also save the above commands to a .bat file for repeated use. Below is the complete content of the file:

@echo off
bcdedit -/set {current} osdevice partition=C:
bcdedit -/set {current} device partition=C:
bcdedit -/set {memdiag} device partition=\Device\HarddiskVolume1
echo Edit complete.
pause

Post-Fix Behavior

After running the commands (or executing the batch script) and rebooting the device:

  • BitLocker can be successfully enabled.

  • The internal script for enabling BitLocker and sending the recovery key to Active Directory functions as expected.
