The Debian Installer is the official installation system for Debian. It offers a variety of installation methods. Which methods are available to install your system depends on your architecture.
Images of the installer for etch can be found together with the Installation
Guide on the
The Installation Guide is also included on the first CD/DVD of the official Debian CD/DVD sets, at:

for debian-installer for a list of known issues.
There has been a lot of development on the Debian Installer since its first official release with sarge resulting in both improved hardware support and some exciting new features.
In these Release Notes we'll only list the major changes in the installer. If
you are interested in an overview of the detailed changes since sarge, please
check the release announcements for the etch beta and RC releases available
from the Debian Installer's
Previously, the installation was split into two parts: setting up the base
system and making it bootable, followed by a reboot and after that the
base-config which would take care of things like user
setup, setup of the package management system and installation of additional
packages (using tasksel).
For etch the second stage has been integrated into Debian Installer itself. This has a number of advantages, including increased security and the fact that after the reboot at the end of the installation the new system should already have the correct timezone and, if you installed the Desktop environment, will at once start the graphical user interface.
The installer will set up systems to use UTF-8 encoding rather than the old language-specific encodings (like ISO-8859-1, EUC-JP or KOI-8).
It is now possible to set up file systems on an LVM volume using guided partitioning.
The installer is also able to set up encrypted file systems. Using manual
partitioning you have the choice between dm-crypt and
loop-aes, using a passphrase or a random key, and you can tune
various other options. Using guided partitioning, the installer will create an
encrypted LVM partition that contains any other file systems (except
/boot) as logical volumes.
If you prefer a graphical user interface, try booting the installer with installgui.
The functionality of the graphical installer is almost identical to the regular installer, only the presentation differs. There is one exception: the graphical frontend does not support setting up encrypted partitions using random keys.
The major advantage of the graphical user interface is that it supports more languages than the regular user interface (newt). Information about the graphical installer and the most important differences between the graphical and regular installer are documented in an appendix in the installation guide.
Note: the graphical user interface is not available for all architectures.
You can use the installer to solve problems with your system, for example when it refuses to boot. The first steps will be just like a regular installation, but the installer will not start the partitioner. Instead it will offer you a menu of rescue options.
Activate the rescue mode by booting the installer with rescue, or by adding a boot parameter rescue/enable=true.
During expert installations you can choose to not set up the root account (it
will be locked), but instead set up
sudo so that the first user
can use that for system administration.
Packages downloaded with the installer are now cryptographically checked using
apt, making it more difficult to compromise a system being
installed over the network.
If the "standard system" is installed, the installer sets up a basic configuration for the system's mail server which will only provide for local e-mail delivery. The mail server will be unavailable to other systems connected to the same network. If you want to configure your system to handle e-mail not local to the system (either to send e-mail or to receive it), you will have to reconfigure the mail system after installation.
The installation system will install a GNOME desktop as the default desktop if the user asks for one.
However, users wishing to install alternate desktop environments can easily do so by adding boot parameters: tasks="standard, kde-desktop" for KDE and tasks="standard, xfce-desktop" for Xfce. Note that this will not work when installing from a full CD image without using a network mirror as an additional package source; it will work when using a DVD image or any other installation method.
There are also separate CD images available that install the KDE or Xfce desktop environment by default.
Thanks to the huge efforts of translators, Debian can now be installed in 47 languages using the text-based installation user interface. This is six languages more than in sarge. Languages added in this release include Belarusian, Esperanto, Estonian, Kurdish, Macedonian, Tagalog, Vietnamese and Wolof. Due to lack of translation updates, two languages have been dropped in this release: Persian and Welsh.
If the graphical user interface is used, an additional eleven languages are supported. These languages can only be selected using this installer as their character sets cannot be presented in a non-graphical environment. The new languages are: Bengali, Dzongkha, Gujarati, Hindi, Georgian, Khmer, Malayalam, Nepali, Punjabi, Tamil and Thai.
Users that do not wish to use any locale can now select C as their
preferred locale in the installer's language selection. More information on
language coverage is available at the
Configuration of language, countries and timezones has been simplified to reduce the amount of information needed from the user. The installer will now guess what the system's country and timezone is based on the language selected, or will provide a limited selection if it cannot. Users can still introduce obscure combinations if need be.
Most of the internationalization and localization tasks that were previously
handled by the
localization-config tool are now included in the
stock Debian installer or in packages themselves. This means that selection of
a language will automatically install packages necessary for that language
(dictionaries, documentation, fonts...) in both standard and desktop
environments. Configuration that is no longer handled automatically includes
the papersize configuration and some advanced X Windows keyboard settings for
Note that language-specific packages will only be installed automatically if they are available during the installation.
A lot of the changes mentioned in the previous section also imply changes in the support in the installer for automated installation using preconfiguration files. This means that if you have existing preconfiguration files that worked with the sarge installer, you cannot expect these to work with the new installer without modification.
The good news is that the
Guide now has a separate appendix with extensive documentation on
The etch installer introduces some exciting new features that allow further and easier automation of installs. It also adds support for advanced partitioning using RAID, LVM and encrypted LVM. See the documentation for details.
The installation system will again offer to install the
popularity-contest package. This package was not installed by
default in sarge but it was installed in older releases.
popularity-contest provides the Debian project with valuable
information on which packages in the distribution are actually used. This
information is used mainly to decide the order in which packages are included
on installation CD-ROMs, but is also often consulted by Debian developers in
deciding whether or not to adopt a package that no longer has a maintainer.
popularity-contest is processed anonymously. We
would appreciate it if you would participate in this official survey, helping
to improve Debian.
