System Details

  • Device: crota360
  • OS: Windows 11 IoT Enterprise LTSC 2024 (24H2, 26100)
  • Firmware Type: UEFI Full ROM
  • Firmware Version: MrChromebox-2603.0 03/29/2026
  • Internal storage type: NVMe

Summary of the Issue

On a Brya, Crota360; Windows 11 does not use fast startup on boot despite shutting down as if it had performed the usual steps to do so before power off. This issue started occurring after installing firmware to the latest 2603.0 mrchromebox release. It did not occur on 2512.2 (previous) or lower.

Steps to Reproduce

  1. Enable Fast Startup

  2. Power off device normally by going to Start > Power > Shutdown

  3. Wait until system is fully off

  4. Attempt to start system

Expected Behavior

Windows 11 should have successfully started up using the cached kernel and state from hyberfil.sys, not perform a cold boot.

I have repeatedly attempted to EC reset and perform a hybrid shutdown through command prompt. I have also tried to use DISM/SFC and toggle hibernation through powercfg. Hibernation type is confirmed to be set as Reduced.

I have found error “0x0C000007B” in Windows Event Viewer. I will be reinstalling windows to see if this fixes the issue.
