title: "Operating System"

## The issue
|
|
|
|
There are only two supported operating systems to run the Supervisor on:
|
|
|
|
- Home Assistant OS
|
|
- Debian 12 (Bookworm)
|
|
|
|
These operating systems are actively tested and maintained, for use with the Supervisor.
|
|
|
|
## The solution
|
|
|
|
You need to reinstall the host machine running the Supervisor on one of the supported
|
|
operating systems.
|
|
|
|
The best approach here is to take a full backup of your current installation
|
|
from the Supervisor panel, then reinstall your host with one of the supported
|
|
operating systems.
|
|
|
|
If the host is a virtual machine or a supported board, you can use our [appliance images](/hassio/installation/).
|
|
|
|
If not, you can get [Debian from here](https://www.debian.org/) and use our [convenience installation script](https://github.com/home-assistant/supervised-installer). Make sure you make it compliant with [ADR-0014](https://github.com/home-assistant/architecture/blob/master/adr/0014-home-assistant-supervised.md), the convenience script will handle most of that for you.
|
|
|
|
When the new host is set up and you can reach the Home Assistant frontend, you can upload and restore the backup you made earlier.
