What’s happening?

· My Roon software won't start up

How can we help?

· I'm having trouble with my Nucleus hardware

Other options

· My Roon software won't start up

Describe the issue

I’ve replaced original roon os drive with compatible m.2 ssd and have used roon os recovery flashed to cf card and installed on new drive using f10 keystroke launch. The new drive will not boot. I’ve tried to modify system bios to prioritize cf card boot, still not able to reboot. I’ve tried to reinstall original m.2 ssd and the nucleus will not boot and does not show up in bios. I’d like to be able to get the original roon nucleus bios settings for a fresh install. Any members have any experience with this? Has any one successfully installed a larger m.2 ssd for the boot volume?

Hello @Daniel_Hill,

Nice to meet you again on our comunity!

Thank you for reaching out and providing detailed context—sorry to hear you’re running into this!

To help you better, could you please let us know the exact model of your Nucleus (e.g., Nucleus One or Nucleus Titan etc.) and the make/model of the M.2 SSD you’re trying to install? That will help us check compatibility and guide you through the next steps.

Do you see the new or old m2 ssd drive as a boot device in the BIOS settings ?

Try using a usb key flashed with the rock installer using etcher. Then when rock is installed, use the support system to request an change to Nucleus.

Also, larger drives work, but you cannot use the extra space, it is just wasted.

@Rugby, thanks for the directions which I did indeed follow prior to opening this ticket.

Curious with what you stated, if the larger OS boot M.2 drives are utilized, why does my current drive
show as almost maxed out at 93% of 55 gb? Also, why would Roon equipe the rev.b nucleus with 2x capacity?

I might have gotten too ambitious as I just installed 32gb of ram and the results were spectacular with
a library of 100K+ files. Using the stock 4gb ram was becoming problematic to say the least.

Hi Vadim

Thanks for having a look at my situation.

I’ve been trying to install a new M.2 SATA OS drive using a Crucial PCIe Gen4 NVMe 2280 M.2 SSD model P310 1TB.

I tried to both restore and write to the drive with a flashed cf with roonbox-linux nuc-4 usb reset file.

From my research, I’ve understood that I would have to initially set up my nucleus as NUC rock and

then a Roon Administrator would be able to bring me back to a Nucleus setting and or rest with the web admin page.

Both times the boot drive was not found.

I did try to direct the boot volume to the usbcf in BIOS as well.

I gave up, and reinstalled the original ssd without a successful boot.

This morning the Nucleus revA did successfully boot. However prior to booting, I did

remove the installed sata music file storage drive. I’m not sure if that has anything to do with system boot restore.

I’m including some screen shots for the original M.2 factory ssd as well as some screen photos of my current

as of this morning BIOS settings. There is also a screen shot from my web admin page for system details.

Thanks, Daniel

Hello @Daniel_Hill,

Let’s try resetting the BIOS settings to default. You can do this by pressing the F9 key while in the BIOS menu to load the default configuration.

After that, please attempt to boot from the original M.2 SSD that was delivered with the Nucleus device.

Let me know how it goes or if you encounter any issues during the process.

I had actually returned BIOS to factory settings using F9, yesterday and in fact repeated this again today without any issues rebooting form the original M.2 SSD, any insight on how to install the larger crucial drive in my nucleus rev.a? Thanks Again

After a successful boot on original M.2 ssd, I’ve reinstalled music sata ssd storage. This prevents a successful boot up. There is some kind of conflict when installing the drive with the system start up. I’ve enclosed a screenshot.

Hi @Daniel_Hill ,

That error is indicative of a kernel panic, the solution for this is usually to reinstall RoonOS.

The unit still boots up properly with no SATA SSD attached?

Also, I noticed that you are using a Gen4 SSD, we typically suggest using a Gen3 one, not sure if this is playing a part in the issue.

Ok based on your last comments. I have removed the music sata drive.
Using the web admin, I have successfully reinstalled the OS.

The unit boots up and shows network connection.

I have then reinstalled the music sata drive and rebooted to the boot failure shown
in the included screen image.

Not sure how to proceed here. System works fine without the sata drive, I’m guessing
that the drive is causing a “kernel panic” in any case I can wipe the drive and keep trying to
reinstall it, however what I would really love is to know is there any reason why I’m not able to
use roon’s roonbox flashed to a cf card to install in the new and larger m.2. Would you be able to go over with me again the instructions. Once the flashed cf card is installed in the nucleus, is
it a complete install or restore, and what key stroke for the install menu, as I’ve not consistently been able to access it. Thanks

Hello @Daniel_Hill,

Thanks for the update!

It sounds like the SATA SSD is currently marked as bootable, which might be causing the system to attempt booting from it instead of your M2 device. The step you can take is to remove the boot flag from the sata SSD partition or change the boot order, which should help avoid this issue.
