🛠️ Fix BitLocker Recovery Loop After BIOS or Secure Boot Changes
BitLocker Recovery Loop Guide 🛠️ BitLocker Recovery Loop – Enterprise Troubleshooting Guide This guide explains how to troubleshoot repeated BitLocker recovery prompts after BIOS, TPM, Secure Boot or hardware changes in enterprise environments. 💡 Root cause: TPM PCR mismatch (especially PCR7 related to Secure Boot) after firmware or boot configuration changes. 🧠 Root Cause Explained (Important) BitLocker uses TPM PCR measurements to verify boot integrity. When firmware, Secure Boot or boot configuration changes, the TPM measurements no longer match → BitLocker triggers recovery mode. BIOS/UEFI update changes firmware measurements Secure Boot keys or DB/DBX changes TPM firmware update or reset Boot order / UEFI configuration changes Docking station affecting hardware hash 🌲 Decision Tree 1. Does BitLocker ask for recovery every boot? → Yes: TPM integrity issue (PCR mismatch) 2. Did it start after BIOS/firmware update? → Yes: Suspend ...
