Persisting GRUB boot slot choice following OS update

Installation
1

I have a PC without UEFI and am using GRUB to manage the boot slots.

Currently I have it booting from Slot A, with the latest OS version in slot B. I can manually select slot B from the GRUB menu and it works. However I can not get any of the HAOS commands to persist the boot slot to B, it always reboots to A. I specifiy using os boot-slot from the CLI.

Using ChatGPT it suggests editing the GRUB files but that feels like the wrong way to do it.

Does HA support at none UEFI install correctly, or if so what is going wrong?

I’ve managed to achieve the end goal by installing a back level version in Slot B (os update --version x.x), manually booting in to that from GRUB menu and then doing an os update from there to install the latest in Slot A. A low risk way of doing it but not ideal. Hopefully there is a better way or some identified improvement to the installation to remove this requirement.
