Installing with the Debian-Installer

For official Debian 12.5 installation media and information, see the bookworm page.

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

To install Debian testing, we recommend you use the daily builds of the installer. The following images are available for daily builds:

Current daily snapshots

netinst CD images (via jigdo)
other images (netboot, USB stick, etc.)


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


If you read only one document before installing, read our Installation Howto, a quick walkthrough of the installation process. Other useful documentation includes:
