Debian is distributed freelyover Internet. You can download all of it from any of ourmirrors.The Installation Manualcontains detailed installation instructions.And, the release notes can be found here.
If you simply want to install Debian, these are your options:
Download an installation image
Download an installation image. Depending on your Internet connection, you may download either of the following: A small installation image: can be downloaded quickly and should be recorded onto a removable disk. To use this, you will need a machine with an Internet connection. 64-bit PC netinst iso; 32-bit PC netinst iso. It is a Debian Live system that run a litle.iso file(we can make more much litle) on the hardware or virtual machine and download the filesystem.squashfs file that is a Full Operating System. Iso file only have a bootable/runnable System to execute processes to download the full system to get in (RAM)memory then is the same Live Systems.
Depending on your Internet connection, you may download either of the following:
- A small installation image: can be downloaded quickly and should be recorded onto a removable disk. To use this, you will need a machine with an Internet connection.
- A larger complete installation image: contains more packages, making it easier to install machines without an Internet connection.
Use a Debian cloud image
- An official cloud image: can be used directly on your cloud provider, built by the Debian Cloud Team.
Try Debian live before installing
You can try Debian by booting a live system from a CD, DVD or USB key without installing any files to the computer. When you are ready, you can run the included installer (starting from Debian 10 Buster, this is the end-user-friendly Calamares Installer). Provided the images meet your size, language, and package selection requirements, this method may be suitable for you. Read more information about this method to help you decide.
Buy a set of CDs or DVDs from one of the vendors selling Debian CDs
Many of the vendors sell the distribution for less than US$5 plus shipping (check their web page to see if they ship internationally).
Some of the books about Debian come with CDs, too.
Here are the basic advantages of CDs:
- Installation from a CD set is more straightforward.
- You can install on machines without an Internet connection.
- You can install Debian (on as many machines as you like) without downloading all packages yourself.
- The CD can be used to more easily rescue a damaged Debian system.
Buy a computer with Debian pre-installed
There are a number of advantages to this:
- You don't have to install Debian.
- The installation is pre-configured to match the hardware.
- The vendor may provide technical support.
Please do not download CD or DVD images with your web browser the wayyou download other files! The reason is that if your downloadaborts, most browsers do not allow you to resume from the point where itfailed.
Instead, please use a tool that supports resuming - typicallydescribed as a
download manager. There are many browser pluginsthat do this job, or you might want to install a separateprogram. Under Linux/Unix, you can use aria2, wxDownload Fast or (on thecommand line)
wget -c URL or
curl -C - -L -O URL. Thereare many more options listed in a comparisonof download managers.

Be sure to have a look at the documentation before you install.If you read only one document before installing, read ourInstallation Howto, a quickwalkthrough of the installation process. Other useful documentation includes:
- Installation Guide, the detailed installation instructions
- Debian-Installer Documentation, including the FAQ with common questions and answers
- Debian-Installer Errata, the list of known problems in the installer
Registered mirrors of the
Note that some mirrors are not up to date —before downloading, check the version number of the images is thesame as the one listed on this site!Additionally, note that many sites do not mirror the full set ofimages (especially the DVD images) due to its size.
If in doubt, use the primaryCD image server in Sweden, or trythe experimental automaticmirror selector that will automatically redirect you to a nearbymirror that is known to have the current version.
