Mini PC Pro from MLLSE problem during boot process?

Installation Home Assistant OS
1

Hello,
I tried to install the HassOS image (haos_generic-x86-64-16.2.img.xz) on a MINI PC M2 Pro from MLLSE. I followed the online instructions using Ubuntu, and I was able to restore the generic file successfully.
By the first boot, a small menu appeared with the title “GNU GRUB Version 2.12.” I selected the first option, and the boot process started correctly. After several lines were displayed, the screen went black, and nothing else happened.
My BIOS (American Megatrends) is version 2.18.1264, and it looks slightly different from the examples shown online. I’m not sure if I missed a specific setting or configuration in the BIOS.
Any guidance would be greatly appreciated.
Thank you for your help!
Best regards,

Hi Otto,

I’ve the same problem and my case I encountered some problems to execute the Ubuntu live. Only in the safe mode it has working.
I don’t know if the problem are the settings in the BIOS or other. But I can say that this mini PC it’s very cheap and slow.
If I don’t find any solution I think that the next use of this PC will to be a bookend.

I had the same problem. I used an AI (chatgpt) to troubleshoot it and the key idea was actually very simple: the system was loading an incompatible GPU driver during boot, which caused the screen to go black before HAOS could finish starting.

What worked for me was:

  1. Boot HAOS in a “safe” or fallback mode (basically without accelerated graphics).

  2. Once in the shell, disable the specific video driver that was causing the issue (in my case it was the Intel i915 module).

  3. Reboot normally.

Hello,
thanks for the input, it avoided me to return my MLLSE M2 Pro (J3710 cpu).
In details, since I was even not familiar: when GRUB starts (keep hitting any arrow to let it prompt the partitions), choose the partition you want to boot, edit it typing “e” then add at the end of the command line:

modprobe.blacklist=i915

Then F10 (or any other command to load the partition).

As per suggest from @catacluj, to make it permanent you need to add it at the end of n.4 partition entries in the grub.cfg file:

<<
At the local “ha” prompt, type “login” then enter.
Then you can use vi to edit said file:
vi /mnt/boot/EFI/BOOT/grub.cfg
vi is not too easy, but not too hard.
