MSI Cubi NUC AI 1UMG wont boot HAOS

[coolnetworks]

Describe the issue you are experiencing

this unit is an U7 CPU with 64GB ram. latest firmware and current as at Oct 2025.

UEFI is on by default in this bios, and secure boot is disabled.

by adding

debug=all

to the top of the grub boot menu, and then

plymouth.enable=0 quiet=0 loglevel=7 \
systemd.log_level=debug systemd.log_target=console \
systemd.journald.forward_to_console=1 \
console=tty1 nomodeset systemd.debug-shell=1 earlycon keep_bootcon

we get a bunch of grub items and at the end it passes off to the kernel with a line

loader/efi/linux.c:238:linux: starting image 0x57ddf198

• nothing happens after that.

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

16.2

Did the problem occur after upgrading the Operating System?

There were similar reports for some Intel Ultra processors having issues booting, see e.g.: #3474

Namely options like VT-d, VMD are known to be problematic combined with some boards/BIOSes. Adding intremap=off kernel parameter might fix that situation too - let me know if any of that works.

Some more research gave me the idea that it might be because of missing x2APIC controller, I've opened a PR that adds it and started a dev build: #4342

I'll update you with instructions how to test it when the build is ready.

The OS image is available here for testing: https://os-artifacts.home-assistant.io/16.3.dev1759838731/haos_generic-x86-64-16.3.dev1759838731.img.xz

Just install it as usual (without changing anything what was suggested in the previous post) and report the results. Thanks!

Sorry for taking so long. @sairon that image works perfectly thank you

@sairon Still has this same problem with 16.3rc-1

I disabled all the security features, but still HA OS boot fails with:
error: unknown filesystem

BIOS configuration:

System:
ASUS NUC14MNKB2 N150

Is the only solution to run HA in docker? :(
