Дальше нам понадобится tftpd (или нечто производное) для передачи самого ipxe и конфига меню. Владельцем каталога с загружаемым файлом, в debian производных системах, должен быть nobody. Содержимое каталога:
1) undionly.kpxe - сам ipxe;
2) menu.ipxe

И теперь осталось дело за малым - заинсталлить на образ/раздел операционки. В арче этот вопрос освещен в вики, проблем возникнуть не должно. А вот с виндой да, проблема, пока так и не поборол.
