@abdel The error message indicates that no pxe boot information is making it to the target computer. Please try to pxe boot with a physical computer. For this test you don’t need to do anything other than get to the fog ipxe menu. Make sure when you pxe boot a physical computer you know if its in bios or uefi mode, because the value entered in dhcp option 67 is specific to the pxe booting computer. For bios computers you need undionly.kpxe in option 67 and for uefi computers you will need ipxe.efi in dhcp option 67.
