Ничего подобного там нет.

an I install Tails permanently onto my hard disk?

This is not possible using the recommended installation methods. Tails is designed to be a live system running from a removable media: USB stick or DVD.

This is a conscious decision as this mode of operation is better for what we want to provide to Tails users: amnesia, the fact that Tails leaves no traces on the computer after a session is closed.
