These are files containing the installer and other software
for the Debian GNU/Linux operating system.
The files in this directory are specifically for
The files here are complete ISO images, ready to use.
Once you have downloaded all the ISO images you want, you will typically need to write them to installation media.
The images described here are sized to be written to writeable Blu-Ray media at a minimum, but may be written to larger media if needed.
For extra convenience, these images may also be written directly to a USB stick. So long as your computer will boot directly from that USB stick, it should start the Debian installer that way.
In most cases it is not necessary to download and use all of these images to be able to install Debian on your computer. Debian comes with a massive set of software packages, hence why it takes so many disks for a complete set. Most typical users only need a small subset of those software packages.
Initially, you will only need to download and use
the first image of a set (labelled as
debian-something-1 to be able to start the
Debian installer and set up Debian on your computer. If there are
more images available here
debian-something-3, etc.), they contain the
extra packages that can be installed on a Debian system (as
mentioned previously). They will not be
bootable and are entirely optional. If you have a fast Internet
connection, you're most likely better off installing any
desired extra packages directly from the Debian mirrors on the
Internet instead of by using these extra images.
edu BD here is a special version of
the BD image that is targeted specifically at 32-bit Intel machines.
It provides a menu to install the Debian Edu Pure Blend without the
need of an Internet connection. See the
Debian Wiki for
There are files here (SHA512SUMS, etc.) which contain checksums of the images. These checksum files are also signed - see the matching .sign files. Once you've downloaded an image, you can check:
For more information about how to do these steps, read the verification guide.
We don't store/serve the full set of ISO images for all architectures, to reduce the amount of space taken up on the mirrors. You can use the jigdo tool to recreate the missing ISO images instead.
This is an official Debian image build and so only includes Free Software.
For convenience for some users, there is an alternative unofficial netinst CD build which includes non-free firmware for extra support for some awkward hardware. Look under /cdimage/unofficial/non-free/cd-including-firmware/ if you need that CD image instead.
See the Debian CD FAQ for lots more information about Debian CDs and installation.
The images here were put together by the Debian CD team , using debian-cd and other software.
