Lenovo ThinkPad displays NO_STR when performing Full Disk Encryption Safe Start

Authors list

Problem

When using DESlock+ v4.8.3 and performing a Safe Start Full Disk Encryption process on a ThinkPad machine the SafeStart countdown screen shows the text NO_STR and the version number in the upper right corner is Version 2.8.  When Windows loads, the Safe Start process will fail returning the error SafeStart detected compatibility issues 0xC00B003D.

Cause

While the workstation is reporting to the Operating System and the Enterprise Server as being a UEFI booting system, the boot process is in fact set to first boot using Legacy Boot (MBR) mode causing the Safe Start process to fail. 

The Boot Mode will be listed as UEFI in the Workstation Details display if you are using an Enterprise Server.

 

Solution

  • Reboot and enter the BIOS of the machine by pressing F1 at boot time.
  • Use the arrow keys to select the Startup section of the BIOS.
  • If the options are set as detailed below this solution will not work for your system and you should contact our support team with details of your problem: KB213 - How do I create a DESlock+ Support ticket?

UEFI/Legacy Boot is set to UEFI

or

UEFI/Legacy Boot is set to Both and the UEFI/Legacy Priority option is set to UEFI
