Select the scenario that applies to you and follow the procedure.

To resolve the issue, do any of the following:

Use FDE Repair CD

  1. Boot the computer to the FDE Repair CD.
  2. After authenticating using an admin account, go to the Recovery console.
  3. On the next window, select Restore Boot.
  4. Reboot the computer. The computer should now be able to boot to the Windows login screen and authenticate successfully.

Use Windows CD

  1. Boot the computer to the Windows CD.
  2. Run the following commands:
    bootrec /fixboot
    bootrec /fixmbr
  3. Reboot the computer. The computer should now be able to boot to the Windows login screen and authenticate successfully.

To resolve the issue:

  1. Boot to Windows using the FDE Repair CD.
     
    Before the Windows boot can be recovered, decrypt the hard disk first. Failure to decrypt the hard disk will result in irreversible data loss.
    1. Boot the affected computer to the FDE Repair CD.
    2. Using an admin account, authenticate to the Repair CD.
    3. Go to the Recovery console.
    4. Select Decrypt Disk to start decrypting.
       
      Do not interrupt the process otherwise irreversible data loss may occur.
    5. Reboot the computer.
    6. After rebooting, select Restore Reboot.
    7. Reboot the computer again. The computer should now be able to boot to the Windows login screen and authenticate successfully.
  2. If the computer still fails to boot, use the Windows CD:
    1. Run the following commands:

      bootrec /fixboot
      bootrec /fixmbr

    2. Reboot the computer.
  3. After you successfully boot to Windows, uninstall FDE using MsiExec.exe:
     
    Uninstalling via TMFDEUninstall.exe will no longer work since after restoring the Windows boot, user is not prompted to authenticate via the FDE preboot screen before proceeding to Windows.
    1. Using the Run window or Command shell, copy and execute the following MsiExec.exe string:

      MsiExec.exe /X{17BACE08-76BD-4FF5-9A06-5F2FA9EBDDEA}

    2. Follow the screen prompts to uninstall FDE:
      1. Answer “Yes” when prompted to uninstall the product.
      2. Agree to close the necessary applications to continue with the uninstallation.
