Windows 10: Bitlocker and BIOS update

Hello, Due to system stability issues, I need to update the BIOS of the motherboard. After reading the instructions on the manufacturer's Asus website, I notice that they strongly recommend disabling Bitlocker encryption, but do not specify if this is only necessary when the encrypted drive is the system drive where Windows 11 Pro is installed, or if it is also necessary to disable Bitlocker encryption for each drive. On my computer I only have one secondary drive encrypted, it is a Seagate IronWolf NAS model disk with little free space left. I tried searching for information on whether i

Automatic windows update with BIOS update triggered bitlocker

Hello Debra Delacroix,

thank you for posting on the Microsoft Community Forums.

An automatic BIOS update during a Windows update can potentially enable BitLocker or trigger a BitLocker recovery if certain conditions are met. This is especially likely if the update changes hardware configurations or settings that BitLocker monitors to ensure system integrity. Here are a few steps you can follow given your situation:

Step 1: Verify BitLocker Status.



1. Access Windows Recovery Environment (WinRE):

- Power on your computer and as soon as the Windows logo appears, hold down the power button to force shutdown. Repeat this process 2-3 times until you see the "Preparing Automatic Repair" screen.

- After diagnosis, go to "Advanced options."



2. Use Command Prompt in WinRE；

- Navigate to "Troubleshoot" > "Advanced options" > "Command Prompt."

- In Command Prompt, type the following command to check the BitLocker status:

This will show whether BitLocker is indeed enabled and on which drives.

Step 2: Look for the Recovery Key in Alternate Locations.

You need to follow the steps in Finding your BitLocker recovery key in Windows - Microsoft Support to find it out.

Important:

• If you are unable to locate the BitLocker recovery key and can't revert any configuration change that might have caused it to be required, you’ll need to reset your device using one of the Windows recovery options. Resetting your device will remove all of your files.
  
• Microsoft support is unable to provide, or recreate, a lost BitLocker recovery key.
  

Step 3: Change BIOS/UEFI Settings.

1. Disable TPM:

- Restart your computer and enter the BIOS/UEFI settings (usually by pressing a key like F2, F12, Del, or Esc during startup).

- Navigate to the security settings and look for TPM (Trusted Platform Module).

- Disable TPM and save changes, then restart your computer.

Step 4: Other Options.

1. Safe Mode:

- Attempt to boot into Safe Mode by holding the Shift key and selecting Restart from the power menu. If you can access Safe Mode, there might be administrative tools to disable BitLocker.



2. Try Automated Recovery:

- In the WinRE, go to "Troubleshoot" > "Advanced options" > "Startup Repair." Follow the prompts to see if Windows can fix the startup issue automatically.

Final Option: Clean Installation.

If no recovery key is found and you cannot disable BitLocker, performing a clean installation of Windows might be your last resort.

Regards,

Lei
