The bootable system image will let you try out Debian immediately. Just flash the provided system image to an SD-card (or USB flash drive) and turn on your Reform with the SD-Card (or USB stick) inserted. You can install Debian to eMMC or NVMe by using the reform-migrate and reform-setup-encrypted-nvme scripts on that system. If you prefer installing Debian using the Debian installer you can flash the d-i image to a USB flash drive and install Debian to your Reform in the same way as you would for other machines. If you already have Debian installed and would like to switch to using Debian Bookworm, you can set up your system to use the apt repository.

In contrast to the Debian system images and apt repository provided by MNT Research, this page provides its content based on Debian stable (Bookworm) instead of unstable for a more reliable computing experience. The disk images as well as the packages in the apt repository are signed with a GPG key that is part of the Debian Developer keyring shipped by the debian-keyring package on your system.
