Installing with the Debian-Installer

For official Debian 5.0.5 installation media and information, see the lenny page.

All images linked below are for the version of Debian Installer being developed for the next Debian release and will install Debian testing (squeeze) by default.

To install Debian testing, we recommend you use the squeeze Alpha1 release of the installer, after checking its errata. The following images are available for squeeze Alpha1:

netinst (generally 135-175 MB) CD images
[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc]
businesscard (generally 20-50 MB) CD images
[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc]

full CD/DVD sets

CD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]
DVD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]

full CD/DVD sets (via bittorrent)

CD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]
DVD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]

full CD/DVD/Blu-ray sets (via jigdo)

CD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]
DVD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]
BD:	[amd64][i386][source]

other images (netboot, USB stick, etc)
[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390]

Or install the current weekly snapshot of Debian testing which uses the same version of the installer as the last release:

full CD/DVD sets

CD: [amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source]

DVD: [amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]
full CD/DVD sets (via bittorrent) — only sufficiently seeded images are listed

CD: [amd64][i386]

full CD/DVD/Blu-ray sets (via jigdo)

CD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source]
DVD:	[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc][s390][source][multi-arch]
BD:	[amd64][i386][source]

If you prefer to use the latest and greatest, either to help us test a future release of the installer or because of hardware problems or other issues, try one of these daily built images which contain the latest available version of installer components.

netinst (generally 135-175 MB) and businesscard (generally 20-50 MB) CD images
[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc]
netinst and businesscard CD images (via jigdo)
[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][sparc]
multi-arch CD images
[iso images][jigdo files]
other images (netboot, usb stick, floppy, etc)
[amd64][armel][hppa][i386][ia64][mips][mipsel][powerpc][s390][sparc]

If any of the hardware in your system requires firmware to be loaded with the device driver, you can use one of the tarballs of common firmware packages. Instructions how to use the tarballs and general information about loading firmware during an installation can be found in the Installation Guide (see Documentation below).

Notes

Before you download the daily built images, we suggest you check for known issues.
An architecture can be (temporarily) omitted from the overview of daily built images if daily builds are not (reliably) available.
For CD and DVD images, an MD5SUMS file is available in the same directory as the images.
For downloading full CD and DVD images the use of bittorrent or jigdo is recommended.
For the less common architectures only a limited number of images from the CD and DVD sets is available as ISO file or via bittorrent. The full sets are only available via jigdo.
The multi-arch CD image supports i386/amd64/powerpc; the installation is similar to installing from a single architecture netinst image. This image also supports installing XEN instances, but only for i386 and amd64.
The multi-arch DVD image supports i386/amd64; the installation is similar to installing from a single architecture full CD image; the DVD also includes the source for all included packages.

After using the Debian-Installer, please send us an installation report, even if there weren't any problems.
