Essa instalação é chamada de instalação autônoma. Você pode usar pré-configuração para responder perguntas de instalação e definir configurações personalizadas.
A partir da introdução :
Preseeding provides a way to set answers to questions asked during the installation process, without having to manually enter the answers while the installation is running. This makes it possible to fully automate most types of installation and even offers some features not available during normal installations.
Cuidado com uma limitação:
Although most questions used by debian-installer can be preseeded using this method, there are some notable exceptions. You must (re)partition an entire disk or use available free space on a disk; it is not possible to use existing partitions.
