[Solved] Boot ISO images over menu.ipxe

[Gelip]

So far I've used pxelinux.0 default menu. Now I want to replace the default menu to menu.ipxe. I'm trying boot ISO image (75.3MB) over menu.ipxe. ISO loading but stop booting and message:

Code:

Loading boot sector... Booting...

What is wrong? This is part menu.ipxe:

Code:

:mxp14
echo Mini WinXP HBCD 14 - AUTOSTART NETWORK & TEAMVIEWER
kernel memdisk
initrd /images/mxp14.iso
boot
goto start

pxelinux.0 working OK with menu default:

Code:

LABEL mxp14
MENU LABEL Mini WinXP HBCD 14 - AUTOSTART NETWORK & TEAMVIEWER
kernel memdisk
append iso
initrd /images/mxp14.iso

Is there any instruction on how to build the menu?
