It's a little be complex.
It's a DVD based installer where I try to change this to be installable via 
The DVD are masterpreloads from a Notebook company. I think you know which :-)

We have a lot of this notebook to install so it's easier to do this via 
network (also different models/types).

OK, now the problem:
You are right, the old versions of the installer (XP and Win7) run under 
BIOS. The new (Win8) require EFI boot.
I test it with BIOS boot, but the preload install script from this company 
check if the boot is EFI or legancy.
If it's not EFI it stop with the info that the boot methode must be EFI. 
Next I tried to boot via some windows pxe methodes and
wimboot to only need some boot files and the wim image. But when I do it 
this way the installer fail with the info that the system
must be booted from CD/DVD.

I tried to change the installer and also found the registry key with the 
boot info, but the installer perform a wpeutil
which set the registry back to 'ramdisk' when I not boot from CD or stored 
iso image in memdisk.

It's very frustrating

Thanks and regards
