0x81000031 error Windows 7

Back to Top

Consider the following scenario:

• You have a computer that is running Windows 7.
• You connect an external hard disk drive to the computer.
• You enable Windows BitLocker Drive Encryption on the system drive.

In this scenario, when you try to back up your files to the external drive by using the Windows Backup and Restore Wizard, you receive an error message that resembles the following:

• "BitLocker Drive Encryption cannot be used because critical BitLocker system files are missing or corrupted.  Error code: 0x81000031"

Cause: This error occurs because the BitLocker Wizard moves Windows Recovery Environment (Windows RE) from the system drive to the external hard disk drive. Therefore, this prevents a backup on the external hard disk.


How to repair?

To resolve this issue, follow next steps:

• 1> Connect the external hard disk drive to the computer. Make sure that the external hard disk drive is powered on.
  
  2> Create a Windows 7 system repair disc. To do this, follow these steps:
  
   > Click Start, type create a system repair disc in the Start Search box, and then click Create a System Repair Disc in the Programs list. Follow the instructions to create the disc.
  
  Note You must have a CD or DVD burner to create a system repair disc.
  
  3> Start an elevated command prompt. To do this, follow these steps:
  
   > Click Start, type command prompt in the Start Search box, right-click command Prompt in the Programs list, and then click Run as administrator.
  
  4> At the command prompt, type the following command, and then press ENTER:
  C:\Windows\System32\REAgentC.exe /disable
  
  5> Disconnect the external hard disk drive.
  
  6> At the elevated command prompt, type the following command, and then press ENTER:
  C:\Windows\System32\REAgentC.exe /enable
  
  Note This operation might fail. In this case, if you have to have access to recovery tools, use the Windows 7 system repair disc that you created in step 2.
  
  7> Reconnect the external hard disk drive to the computer.
  
  8> Start the Backup and Restore Wizard to back up your files and data to the external hard disk drive.
