@AsGF2MX Well where we have seen this issue before is in then hand off between iPXE mode and the uefi firmware to launch the kernel. You could try newer iPXE kernels that may have a workaround for buggy firmware. Typically a firmware update fixes the issue. But if you have the latest firmware we need to look elsewhere.
As an alternative, you could switch the device back to bios (legacy) mode for capture and deploying. I know its a bit of a pain, but that method works too. You can capture and deploy a uefi image in bios mode no problem. You just have to be in the right firmware mode to boot the OS.
While this isn’t a solution (and not sure if it worked in 1.3) we have been able to usb boot right into FOS bypassing PXE loading altogether. There are some caveats with this approach but it does work (for sure) with the 1.4.x branch. https://forums.fogproject.org/topic/7727/building-usb-booting-fos-image Look at the FOG forum chat for an example image file. You will want to install the kernels and inits from 1.3.x series on the usb flash drive as well as update grub.cfg according to the tutorial to see if it works for you.
One last thing I thought of, make sure secure boot is disabled. The FOS kernels are not signed by microsoft so secure booting is not viable right now.
