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 CD 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.
netinst CD here is a small CD image that
contains just the core Debian installer code and a small core set
of text-mode programs (known as "standard" in Debian). To install
a desktop or other common software, you'll also need either an
Internet connection or some other Debian CD/DVD images.
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 Debian image build only includes Free Software where possible. However, many systems include hardware which depends on non-free firmware to function properly so this build also includes those firmware files for those cases. See the Debian Wiki non-free firmware page for more information.
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.
