Operating systems

Every system the reinstall form offers, one page each: how to select it, what it gives you on the first boot, and the trap that catches people on it.

The reinstall form carries eleven tiles, and one system that hides behind another. Each page below covers a single system: where it sits in the panel, what the image gives you on the first boot, and the one thing that catches people out on it.

The form itself, its partitioning, its software RAID and its password field, is described once in reinstalling your OS.

Two things worth knowing before you choose ​

Proxmox VE has no tile of its own. It is a version of the Debian tile, PVE 9. Looking for a Proxmox tile and not finding one is the usual way to conclude, wrongly, that we do not offer it.

A tile opens on one version, not on its newest. Open the list on the tile rather than accepting what is displayed. Two tiles carry no list at all, Arch Linux because it rolls and VMware because it offers a single version.

Note

A system we do not carry as a template installs all the same: upload its image from the ISO Upload tab and run the installer over the console.
