Thanks @george1421, will look into this especially the USB to ethernet (will have to purchase though).

@sebastian-roth Thank you. I have not exchanged .efi for .*pxe, it’s what’s in the configuration by default. I’ve only added the “authoritative;” line and changed the UEFI 64 files to intel.efi instead of ipxe.efi. Also, I’ve also used snponly.efi which returns the same result with intel.efi. I decided to use snponly.efi for the meantime while on testing stage.
