I downloaded the MS Windows AIK to generate the autounattend.xml file.
I was able to start the setup of Vista and complete the installation,
to install the software I would like to deploy within my dvd, but not
to start the OS.
Just after the latest reboot, when the last app is installed, the OS
on the next reboot show me a dialog that informs  the impossibility to
complete the installation process. Pressing ok return a reboot and
again the message.

Below there is the file I generate. Some help?

In particular
