Hi! I keep getting this message at every startup, both reboot and cold start: Windows BitLocker Drive Encryption Information The system boot information has changed since BitLocker was enabled. You must supply a BitLocker recovery password to start this system. Confirm that the boot changes to this system are authorized. If the changes to the boot system are trusted, then disable and re-enable BitLocker. This will reset BitLocker to use the new boot information. Otherwise, restore the system boot information. ENTER=Continue How do I find the root cause to the problem? It's been a while ( several weeks) since I connected an extra monitor. In Device manager, there are no devices needed to be installed. I have not disabled and enabled Bitlocker. I want to avoid decrypting and encrypting the C drive if possible. However, it is still connected, but I have not installed the new monitor, because my display card does not support three monitors. Could this be a possible cause to the problem? Freddy

There is a similar case.
