CAUTION
●
With BitLocker features enabled, modifying the system configuration
(hardware or firmware settings) may render the system inaccessible.
The system may enter Recovery Mode and require a 48-digits
recovery password to return to normal operation. Ensure that you
suspend BitLocker drive encryption before maintaining the server.
● When suspended, BitLocker uses a plain text key instead of the
Trusted Platform Module (TPM) to read encrypted files. Keep in mind
that information on this drive is not secure until BitLocker has been
re-enabled.
▶
Ask the system administrator to suspend BitLocker-protection on the system
volume, using the
BitLocker Drive Encryption control panel item.
This will temporarily disable BitLocker for maintenance purposes. The
volume will not be decrypted and no keys will be discarded.
▶
Click Start - Control Panel - System and Security - BitLocker Drive
Encryption to open the BitLocker Drive Encryption.
▶
Select the system volume, and click Suspend Protection .
▶
Click Yes to confirm that your data will not be protected while BitLocker is
suspended.
In order to determine which features are accessible through the
BitLocker setup wizard, it may be necessary to modify the BitLocker
Group Policy settings. For more information on how to suspend
BitLocker drive encryption, see the Microsoft TechNet library at:

5.2.2 Disabling the boot watchdog
The boot watchdog determines whether the OS boots within a preset time
frame. If the watchdog timer expires, the system will automatically reboot.
If the system is to be started from removable boot media for firmware upgrade
purposes, the boot watchdog needs to be disabled before starting maintenance
