Hardware swap - now unable to boot in to Unraid

Featured Replies

Hey guys, I could use a hand. I replaced CPU/MB/RAM recently and am moving Unraid to a new setup. Struggling with getting Unraid to even boot though. I have all storage unplugged, running on iGPU instead of discrete and a single stick of (known good) RAM.

 

To troubleshoot, I put a spare M2 ssd in the box and installed windows 11 - this seems to work fine, however Unraid freezes during boot as shown. It doesn’t write any logs to the USB so I’m confused as to what’s going on. I also used the usb creation tool to flash this USB with the latest Unraid and it should be running completely vanilla latest version.

 

Any pointers? I’m probably 8 hours deep of trying various combinations of hardware and BIOS settings at this stage and I’m starting to get desperate. Already swapped RAM, reflashed BIOS, tried with and without CSM support and legacy vs. UEFI options. Running a 10900k on a Gigabyte Aorus Vision D X590 board.

 

I’m almost certain the hardware layer is fine, I can run Prime95 in Windows 11 and everything is good.. Just unRAID is sticky for some reason.

No dice, unfortunately. UEFI mode still does the same thing, legacy just goes to a blank screen and sits there.

 

Tried with 2 USB sticks now, created on both Windows/MacOS -- have also tried v6.10.3. Fast boot makes no difference to either mode.

 

Don't suppose you have any other ideas?

Have you tried another port? USB2 port is more reliable.

 

Can you boot another OS using USB on that hardware?

I've tried them all at this stage -- don't think this motherboard has USB 2.0 specifically, nor any way to disable the USB 3.x ports.

Good point, but no. I just tried putting Ubuntu on a USB via Rufus and I get the initial splash screen where I can hit "try Ubuntu", but immediately blank afterwards. This is the same behaviour as unRAID, so I don't think it's unRAID specific.

 

Weirdly on that PC I can put Windows 11 on USB, boot, install and use the OS without issue.

 

.. This is really confusing.

The USB in question came out of the working unRAID server before I rebuilt, so yes. However I flashed it since during testing. Will give it a go on another system now.

Just to follow up, I can boot both Ubuntu and unRAID USB sticks from another machine without issue -- so that means it's just something weird with this new system I'm trying to migrate to.

 

CPU: Intel 10900k

MB: Gigabyte Z590 Vision D

 

It's just so odd that it can boot Windows 11 install media cleanly, but anything *nix it immediately hangs after GRUB is used. 

  • Author

Further down the rabbithole, if I use Rufus to burn the Ubuntu ISO to a spare HDD, and connect this via SATA (to remove anything relating to USB boot, compatibility, etc.) I get the same exact result. Hangs after the "Try or Install Ubuntu" option in GRUB.

 

I'm almost ready to give up and I'd be suspecting a hardware fault, except for the fact that I can boot and run Windows 11 without a single issue.

 

I have never seen anything like this before 🤦🏻‍♂️

Often still provided but on internal header. Not clear it would matter though.

 

BIOS update?

  • Community Expert

I thought I remember reading that Fast Boot had to be disabled in the BIOS when booting Unraid?

BIOS is latest, made sure of that and also reflashed after reconfiguration just in case unfortunately 😔

 

Anyway, I've thrown in the towel and given up. Moving to a spare rig I had that the Mrs was using and transplating a bunch of components. Would have been nice to have 10/20 cores but will go with the i5 12400F instead. Also solves my issue with needing a third M2 slot, so it's not a complete loss.

 

Thanks for your help. I guess this one remains unsolved 🤷🏻‍♂️

That's what I thought too, however I tried toggling it on/off as per the guide with no change.

 

Try switching on or off any Fast Boot feature.
