The Debian Installer is the official installation system for Debian. It offers a variety of installation methods. The methods that are available to install your system depend on its architecture.

Images of the installer for bookworm can be found together with the Installation Guide on the Debian website.

The Installation Guide is also included on the first media of the official Debian DVD (CD/blu-ray) sets, at:

3.1. What's new in the installation system?

There has been a lot of development on the Debian Installer since its previous official release with Debian 11, resulting in improved hardware support and some exciting new features or improvements.

If you are interested in an overview of the changes since bullseye, please check the release announcements for the bookworm beta and RC releases available from the Debian Installer's news history.

3.2. Cloud installations

The cloud team publishes Debian bookworm for several popular cloud computing services including:

  • Amazon Web Services

  • Microsoft Azure

  • OpenStack

  • Plain VM

Cloud images provide automation hooks via cloud-init and prioritize fast instance startup using specifically optimized kernel packages and grub configurations. Images supporting different architectures are provided where appropriate and the cloud team endeavors to support all features offered by the cloud service.

The cloud team will provide updated images until the end of the LTS period for bookworm. New images are typically released for each point release and after security fixes for critical packages. The cloud team's full support policy can be found here.

More details are available at and on the wiki.

3.3. Container and Virtual Machine images

Multi-architecture Debian bookworm container images are available on Docker Hub. In addition to the standard images, a slim variant is available that reduces disk usage.

Virtual machine images for the Hashicorp Vagrant VM manager are published to Vagrant Cloud.
