Windows 2012 - Boot Fail (System Reboot)

[Fr3DBr]

Hi, guys.

I'm currently trying to provision a server using windows 2012.

I'm using the following script :

#!ipxe

kernel http://$server/gpxelinux/wimboot
initrd http://$server/proxy.php/bootmgr.exe bootmgr.exe
initrd http://$server/proxy.php/bcd bcd
initrd http://$server/proxy.php/boot.sdi boot.sdi
initrd http://$server/proxy.php/segmono_boot.ttf segmono_boot.ttf
initrd http://$server/proxy.php/segoe_slboot.ttf segoe_slboot.ttf
initrd http://$server/proxy.php/wgl4_boot.ttf wgl4_boot.ttf
initrd http://$server/proxy.php/boot.wim boot.wim
boot

However, as soon it loads (100% of boot.wim)
the server just reboot and it doesn't boot the image.

This is working fine with windows 2008 R2, but not with windows 2012 R2, is there anything I might be missing that could cause this ?
