HI Sebastin,

Yes, the secure boot is disabled.

Hello,
I am receiving two messages when I try to image or register a computer with FOG. I can IPXE Boot using UEFI just fine. I get to the FOG menu. I choose either to register or deploy the image. If I choose register I get one of the two error messages depending on the brand of computer I am using.

If I am trying to capture an image or deploy an image using an HP computer I receive the following error message.
Could not boot: Exec format error (https://ipxe.org/2e008081)

If I am trying to capture an image or deploy an image using a Lenovo mini desktop computer I receive the following error message.
IFog: Error 0x7f048283 (http://ipxe.org/7f048283)

I have updated to the latest version of IPXE, but I am still receiving the errors. I can capture and register computers just fine using IPXE and Fog when booting with Legacy mode. The errors only happen using UEFI PXIE booting. I would like to get this working. Please let me know what I can do to fix it.
