Shows the list of components to the user during installer operation,
and starts a component when it is selected. Main-menu's
questions are set to priority medium, so if your priority is set to
high or critical (high is the default), you will not see the menu. On
the other hand, if there is an error which requires your intervention,
the question priority may be downgraded temporarily to allow you
to resolve the problem, and in that case the menu may appear.
You can get to the main menu by selecting the “Back” button
repeatedly to back all the way out of the currently running component.
Shows a list of languages and language variants. The installer will
display messages in the chosen language, unless the translation for
that language is not complete. When a translation is not complete,
English messages are shown.

Looks for ISO file systems, which may be on a CD-ROM or on the
Presents a list of Debian archive mirrors. The user may choose
the source of his installation packages.
Checks integrity of a CD-ROM. This way the user may assure him/herself
that the installation CD-ROM was not corrupted.
Lowmem tries to detect systems with low memory and then does various
tricks to remove unnecessary parts of
debian-installer from the memory (at the
cost of some features).
Anna's Not Nearly APT. Installs packages which have been retrieved
from the chosen mirror or CD.
Allows the user to partition disks attached to the system, create file
systems on the selected partitions, and attach them to the
mountpoints. Included are also interesting features like a fully
automatic mode or LVM support. This is the preferred partitioning tool

Installs the most basic set of packages which would allow
the computer to operate under Linux when rebooted.
Detects currently installed operating systems on the computer and
passes this information to the bootloader-installer, which may offer
you an ability to add discovered operating systems to the bootloader's
start menu. This way the user could easily choose at the boot time
which operating system to start.
Installs a boot loader program on the hard disk, which is necessary
for the computer to start up using Linux without using a floppy or
CD-ROM. Many boot loaders allow the user to choose an alternate
