Issue Deploying Image To A Specific Laptop Brand

[AngryITGuy]

Have been using Fog for a couple of years now and it has been working flawlessly for us until a couple of days ago.

Fog is installed on Ubuntu via the git method, Fog is running version 1.5.10.11 with kernel 6.12.35 and we use the ipxe.efi boot file

We have secure boot enabled on all our devices and Fog has been configured to work with this using signed images and deployment files.

We have a single image for Windows 11 and that has been deployed without issue to a load of Dell laptops and desktops. We have also managed to deploy the image to some Stone desktops.

The Stone laptops are proving problematic. They PXE boot and join the task and the image is deployed fine but as soon as the device reboots it hangs with the manufacturers logo displayed on the screen and refuses to post.

I can’t get in to the BIOS unless I pull the hard drive, by some fluke if I put the drive back in the machine will boot but then after a reboot it hangs again. On some rare occasion it will actually continue to work.

I don’t think the issue is with Windows 11 as I can deploy a Windows 10 image and go through the update process and install Windows 11 and the laptop is happy but this isn’t an ideal solution.

I am wondering if the task end sequence and clean up is causing some kind of issue but I don’t really know where to start. As I have said already these laptops worked fine with the Windows 10 image.

Has anyone seen this issue before and able to offer some much needed advice to resolve the issue please?

Thanks
