This could happen if your iso is built for a legacy BIOS and the machine is in UEFI mode.
For a flash drive the UEFI platform would enable the CSM, which emulates legacy BIOS mode.

Best check the BIOS settings of the machine so see if it is in UEFI mode.
If it is in UEFI mode, you can either:
1) Switch the BIOS into legacy mode.
2) Build the .iso with UEFI support. For this look for a patch named
     "allow to build ISO image with EFI support (ipxe.eiso)"
   from Christian Hesse.
