in order to encryptThe Scenario
I have amended the disk partition configuration on my computer, now I need to run the MBAM (Microsoft BitLocker Administration and Monitoring – the enterpise implementation of BitLocker) client in order to encrypt the C drive.
The MBAM client launches OK and I can set a PIN, but when I click proceed with the encryption of my C drive it fails with the following error:
Reviewing the MBAM event logs (Event Viewer > Applications and Service Logs > Microsoft > Windows > MBAM > Admin logs). There is the following associated event:
Event ID: 2
Error Code: 0x80310052
Details: 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.
In my case this is a result of me changing the size of the system partitions, so Windows becomes confused about where it should store the BitLocker BDE files. To repair this complete the following:
- Open an elevated command prompt and type: bcdboot %systemdrive%\Windows (requires a reboot but do not do so yet).
- Open Explorer, Go to C:\Windows\System32\Recovery and rename REagent.xml to eg. REagent.old.xml.
- Reboot computer.
- Rerun MBAM client.
