When initrd WinPE.wim IPXE hung up

Not trying to step on any boundaries or anything, but if it's requesting a load out to boot\undionly.kpxe it seems, to me, that it's attempting to boot from UEFI/EFI methods which wouldn't work for the undionly files. You'd need to use snp.efi, snponly.efi, or ipxe.efi.
