HA OS installing on Intel Atom minipc

Hello everyone! I’m trying to install HA OS on a mini-PC with an Intel Atom processor. Previously, it was running Supervisor, but now I want to install HA OS because of deprecation. However, the installation isn’t working — it seems the issue is the lack of UEFI. Tell me, is there a way to install the OS, or I need to replace the computer with a newer one?

One of options is to install proxmox and then HA into it’s VM. Benefits that you’d be able to run more things beside HA, and also a bit more control over HAOS (remote restart…).

If your mini PC use an Atom CPU and do not support UEFI, then it might also not be a 64bit CPU.

32bit CPUs are also hit by the deprecation.

It is Atom D525
