You may see a dialog box that says “The installation program is
determining the current state of your system and the next
installation step that should be performed.” This is a phase in
which the installation program automatically figures out what you
probably need to do next. In some cases, you may not even see this
box.
During the entire installation process, you will be presented with
the main menu, titled “Debian GNU/Linux Installation Main Menu.” The
choices at the top of the menu will change to indicate your progress
in installing the system. Phil Hughes wrote in the _Linux
Journal_[1] that you could teach a chicken to install Debian! He
meant that the installation process was mostly just _pecking_ at the
_Enter key_. The first choice on the installation menu is the next
action that you should perform according to what the system detects
you have already done. It should say “Next,” and at this point the
next step in installing the system will be taken.
