· My Roon Nucleus has a fixed ip address I cannot access it to switch to DHCP? I have tried every possible option from the community, searching online etc.. I wanted to upgrade my Nucleus but cannot do so until I get access. The data is on a SSD drive can I remove that drive and place in a new Nucleus and not lose the data? do you offer any upgrades that would allow me to send to you for transfer?
I tried that the message in top left says no bootable device detected. it came up once with ROON middle of screen and setup/bootable top right corner but went to non bootable device again. I have reset multiple times same problem.
Thanks for writing in, and for the details so far, Mike.
resetnetwork only works once RoonOS has booted. “A bootable device has not been detected” means the BIOS isn’t finding the internal drive that RoonOS lives on, so the static IP isn’t the problem we’re solving anymore, the unit isn’t starting up. The fact that you saw the ROON screen once and then lost it again usually points to the internal M.2 drive beginning to fail.
Two things would help me get you to the right fix:
Your Nucleus model (Nucleus, Nucleus+, revision if you know it), serial number, and roughly when you bought it.
With the HDMI display and keyboard still connected, power on and tap F2 as soon as you see the ROON logo. That takes you into BIOS, under Advanced, check whether an M.2 or SATA drive is listed. Let me know what you see, or send a photo.
In the meantime, one piece of good news: your music files are on a separate internal SSD from the operating system, so they’re not affected by this and can be moved to another server. Do you have a Roon backup saved anywhere (Settings → Backups)? That’s what carries over your library edits, playlists, and history, if you don’t have one, that’s the piece worth protecting first, and it changes what we’d recommend trying next.
Thanks for the serial number, that helps. Before we talk about replacements/repairs, I want to narrow down one thing, because there are two different problems that look identical from the outside and only one of them needs new hardware.
First, a quick clarification: when you pressed F2 and saw only the SATA drive, was that the boot order list, or the storage device list under the Advanced section? A drive can drop out of the boot order while still being perfectly healthy, that just means the boot files are damaged, which we can repair. Its absence from the storage device list is the more serious finding.
Two things to try, in this order:
1. Reset the BIOS to defaults. Press F2 to enter setup, then F9 to load defaults, F10 to save and exit. Let it reboot and check the storage device list again. This rules out a settings problem masking a healthy drive.
2. Run RoonOS Recovery from a USB stick. Instructions here:
You’ll need a spare USB drive and another computer to write the image. When the recovery menu appears, choose Recover RoonOS, not Reinstall. Recover repairs the operating system while leaving your database and settings intact; Reinstall erases them.
This step tells us what we need to know either way. If recovery runs and completes, the drive was fine and you’re back up with your library intact. If recovery starts but can’t find the internal drive to write to, that confirms the drive itself has failed and we’ll move to replacement.
One thing I want to flag now, so it isn’t a surprise. Your music files are on the separate SATA drive and are not at risk. But your Roon Server database, playlists, play history, album edits, favorites, lives on the internal M.2, and you mentioned you don’t have a backup. If that drive has failed, that database is likely unrecoverable and you’d be rebuilding your library from your music files. It’s not the end of the world, but I’d rather tell you upfront than after the fact.
That’s also why I’d hold off on opening the case to reseat the drive for now. If it does come back to life during the recovery attempt, that’s your one opportunity to pull a backup, and I’d like to preserve that chance.
Could you also let me know which model you have, Nucleus, Nucleus+, or Nucleus One/Titan?
Circling back on this, have you had a chance to try the BIOS reset we mentioned, F9 to load defaults, then F10 to save and reboot, and check whether the internal drive shows up in the storage device list afterward? If you have not already, the next step is to run the RoonOS Recovery USB and choose Recover RoonOS, since that will tell us whether the internal drive can still be written to without wiping your database. Could you also let us know whether you were looking at the boot order list or the storage list in BIOS, and which model you have, Nucleus, Nucleus+, or Nucleus One/Titan?
