Hi there, I’m getting this same issue on Dell Vostro 5402 and Kaspersky Endpoint Security 11.5 for workstation. Tried with FDE Test utility, it’s just stop in black screen with 3 dots upper left on screen even I waited for a long time. I must power off and power on again to boot to windows. After one more time auto-reboot, the report is: [MAJOR] Preboot environment was restarted before tests.
