Cant get to either console after enabling GPU

[NAS-newbie]

I rebuilt my UnRAID system a few days ago with a new CPU/MOBO and it have worked perfectly until I tried enabling CPUs Quick Sync (just downloaded a plugin that did this as well as another plugin that provided a dashboard information about GPU) with the intention of later trying it with Plex and for a completely different reason had to restart the server. I initiated this cleanly from the web console but after this I cant connect over HTTP and the native machine console does not show anything even during UnRAID boot (maybe a natural consequence of enabling GPU that I was not aware of or the system crashed/hang during boot) 😞

 

Is there a way to force UnRAID into "safe boot" (or perhaps enable a serial console or in some other way debug the problem) in this situation or do I have to rebuild a new USB stick (my backup is quite old so would preferably like to avoid that)?

There's a safe mode option right on the boot menu

But I dont get to the menu (or at least cant see it as the terminal screen is all black)....

Connect a monitor and you will see the boot menu.

I have a monitor connected and could see the menu choices before I encountered this problem. Now nothing is displayed when UnRaid boot starts.

That menu appears before Unraid starts to boot, do you see the board BIOS/post messages?

[NAS-newbie]

Yes BIOS show normal message to enter it by pressing del but then screen goes blank. No complaint that OS image is not bootable so assume UnRaid boot start but hang or console directed "elsewhere" (or both eventually as machine do not reach DHCP and get an IP as before)....

 

Does UnRaid boot if it for some reason finds no graphics board/chip (headless)?

It should, but I don't get how you don't see the Unraid boot menu, since that is displayed for 5 seconds before Unraid starts to boot.

I temporarily added a video card (in addition to the built in one on the CPU) and then I got to the console and UnRAID also booted as it should again in normal mode. I then did a fresh backup of the flash drive just in case and removed the video card again and then it still boots as it should so cant reproduce the problem. Lets hope it was a one-time thing that will not come back and haunt me again 🙂
Thanks for the help anyhow!
