Hi,

Below is a updated script, and some information:

#!ipxe

imgfree
kernel wimboot pause gui
initrd boot/rombl.bcd BCD
initrd boot/boot.sdi boot.sdi
initrd sources/winpe.wim winpe.wim
boot

pxeboot.n12 should not be used or existing.
bootmgr.exe is automatically extracted from supplied .wim

imgfree is added to make sure the "default" file is not added to the cpio
that wimboot uses

Are you sure that your bcd refers to winpe.wim?
A known working and minimal BCD can be found at:
https://github.com/NiKiZe/wimboot-bcd/blob/bcdgen/PXEBCD
but it uses the name boot.wim instead.
