| Description | No volume master key was retrieved in a key file during restart. |
| Event Information | According to Microsoft : Cause This event is logged when No volume master key was retrieved in a key file during restart. Resolution Disable and re-enable BitLocker to repair keying information BitLocker entered recovery, and a user has successfully completed the recovery process by using a recovery key (stored on a USB flash drive) or a recovery password (entered manually at the recovery screen). The most recent recovery session happened because the BitLocker key needed to authenticate and unlock the volume could not be retrieved or was corrupted. Although data corruptions can occur, they are rare. This is most likely a hardware error. First, disable and re-enable BitLocker. This will recreate the keying material. If BitLocker continues to enter recovery for the same reason, you need to repair or replace hardware components. To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority. To disable and re-enable BitLocker to recreate volume metadata 1.Click Start, and then click Control Panel. 2.Click Security. 3.Click BitLocker Drive Encryption. 4.If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue. 5.Click Turn off BitLocker. 6.Click Disable BitLocker. 7.In the BitLocker Drive Encryption window, click Turn On BitLocker. 8.Close the BitLocker Drive Encryption window. Caution: We strongly recommend that all important data be backed up regularly. Verify To verify that BitLocker has started successfully: 1.If the computer is not running, start the computer. 2.If BitLocker has been configured to use a USB flash drive, insert the USB flash drive. If BitLocker has been configured to use a PIN, enter your PIN when prompted. 3.Verify that Windows Welcome Screen, Logon Screen or Desktop appears. This indicates that BitLocker has correctly unlocked the Windows operating system volume. 4.Log on to Windows and access any data volumes that are encrypted with BitLocker. Note: Data volumes can be configured to be automatically unlocked or to require manual unlocking. |
