How to Fix Windows 11 BitLocker Recovery Boot Loop After Updates

Cumulative Windows 11 updates (such as KB security patches affecting Secure Boot certificates or EFI system partitions) frequently trigger BitLocker recovery screens upon reboot. When BitLocker fails to recognize the trusted Platform Configuration Registers (PCRs) from TPM 2.0, Windows gets stuck in a continuous recovery loop. In this troubleshooting guide, we walk through how to bypass the loop and repair system integrity.

• TPM PCR Validation Mismatch: Boot component updates alter boot manager signatures before BitLocker unseals encryption keys.
• EFI Partition Space Exhaustion: Smaller 100MB EFI boot partitions run out of free space during patch staging.
• Corrupted Update Staging: Interrupted updates leave system components in a pending/unresolved boot state.

1. Retrieve your 48-digit BitLocker recovery key from your Microsoft Account at account.microsoft.com/devices/recoverykey.

2. Type the recovery key into the screen and press Enter to allow Windows to boot into Recovery Mode.

3. If the loop repeats on restart, force boot to Windows Recovery Environment (WinRE) by interrupting boot 3 times, then navigate to: Troubleshoot > Advanced Options > Command Prompt.

From the WinRE Command Prompt, execute DISM and System File Checker to repair corrupted component stores:

dism /image:C:\ /cleanup-image /restorehealth
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

To prevent BitLocker from asking for the key on every reboot while Windows finishes installing patches, suspend BitLocker protection for 1 reboot session using manage-bde:

manage-bde -protectors -disable C: -rebootcount 1

On Dell, HP, and Lenovo devices, BIOS settings can shift during firmware updates:

• Reboot PC and enter BIOS setup (F2, F10, or Del key).
• Navigate to Security > Secure Boot Configuration.
• Ensure Secure Boot Mode is set to Standard and Platform Mode is User Mode (do not leave in Setup Mode).
• Verify TPM 2.0 Security Chip is Enabled and Active.

If the recovery loop started immediately after a cumulative update, uninstall the recent patch from WinRE Command Prompt:

wusa /uninstall /kb:5074109 /quiet /norestart

By unlocking the drive with your recovery key, running offline DISM/SFC repairs, and temporarily suspending manage-bde protection, you can break the BitLocker boot loop and restore full system stability.
