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

I have done some additional troubleshooting and changing the boot file to snponly.efi didn’t work but turning secure boot off got things working again.

We have always been able to image with secure boot enabled, as I have inherited this setup I assume my predecessor has followed this guide to configure Fog with secure boot

I am sure I have updated the kernel previously without issue so what have I done wrong this time?

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 5.15.93 and we use the ipxe.efi boot file

Got a couple of Stone laptops that refused to boot in to Windows after being imaged, thought the issue was down to the kernel so it was updated to 6.12.35

After the kernel update we were unable to deploy an image at all, reverted back to the original kernel but the problem persists.

When trying to deploy an image we get the following errors

Could not select: Exec error (https://ipxe.org/2e008081)
Could not boot: Exec format error (https://ipxe.org/2e008081)
Could not boot: Exec format error (https://ipxe.org/2e008081)
Chainloading failed

We can check in to the Fog Menu when we PXE boot with a client, allowing us to register, delete and inventory a host but we can’t seem to deploy an image.
