Proplem with Empire EFI

[aatkco]

Hi Friends,
I had proplems installing Leopard Distributions like iPc , iAtkos on my pc so i get an idea from a user "Sweaty" To use empire efi , i think it's a genius app to fresh install snow leopard on pc's .
so i burned empire efi and snow leopard retail dvd and started installing but i got install failed , i tried again and i got the same message :

I am installing into a usb hdd ( it's an internal hdd and connected with ide to usb connecter ) , active , primart and formatted to one guid partition .
I don't know what is the proplem , so i took a screenshot from the installer log which describe the error it may help :

Thanks
