Work around To Unlock 

      
To terminate this BitLocker recovery loop, BitLocker must be suspended from within WinRE. To do so, follow these steps:

• On the page where you are asked to enter the recovery key, choose the Skip this drive link at the bottom. You should be presented with a menu that will let you get to a command prompt (The sequence is Advanced options -> Troubleshoot -> Advanced options -> Command prompt).
• Once you have a command prompt, use the following command to check the BitLocker status of the C: Drive:
  • manage-bde -status c:
• If the status is returned as locked, you must use the following command to unlock it using your recovery password:
  • manage-bde -unlock c: -rp your 48-digit recovery password
• Once the drive is unlocked, you must use the following command to suspend protection:
  • manage-bde -protectors -disable c:
• Exit and reboot.
• The computer should now successfully boot Windows. Once there, use the BitLocker control panel to resume BitLocker protection.
