There's a few errors after grub loads that I'm not sure I should care about but mostly I don't know what this unknown device is only appeared after moving house and carefully moving my box and everything so as to not damage it but seems something happened. I'm hoping a clean install will fix it but maybe it's another issue. I don't know what this unknown device is and all my pools import properly and are accessible.
