I solved that Issue.
SOLUTION:
I have imported an ISO image in my SOI but the product key VLK was not valid when the windows setup stats so i take one from the product.ini file.
I noticed after reading the tecknet that in the unattented file the product key will determine witch .wim image can be instilled, if the key is wrong not .win image is available during windows setup.
I get back to the product.ini and pickup anther key, I imported it in my OS license key in the console and i try the scripted OS install again this time the setup start normally.
Thnks a lot for your help
