ROCK: Updating and Configuring BIOS On Your NUC

Hello @Julie_Meikle

Thank you for reaching out! Just to reassure you, it is completely normal and expected for the BIOS settings to reset to their factory defaults when you replace the CMOS battery.

Geoff has pointed you in the exact right direction! Since the BIOS was wiped, you simply need to reconfigure it so it knows how to boot Roon OS (ROCK) with your SSD.

Please follow the step-by-step instructions in the guide Geoff linked: ROCK: Updating and Configuring BIOS On Your NUC

Once you have updated those settings, save the changes and exit the BIOS. Please let us know if your system boots up normally after that, or if you are still running into any trouble!

Thanks. I have connected to Nucleus to USB keyboard and TV/monitor via HDMI. The Roon logo appears with the instruction F2 Enter Setup; F7 BIOS F10 enter Boot Menu

However hitting the F2 key causes this to disappear and the screen go dark….no text. The other two options seem to offer something….F7 I can read, but F10 is off screen and I can just see a text box.

How do I proceed please? Thanks

Hello @Julie_Meikle

Just following up on your situation regarding the new SSD.

Could you clarify one important detail for us: Did you reinstall the Roon operating system (ROCK) onto this new SSD after installing it into the NUC?

I ask because if you replaced the primary M.2 drive (where the system is stored), the new drive is completely blank out of the box. Simply configuring the BIOS will not be enough to get the Core to boot up—it needs the operating system installed onto it from a USB flash drive first.

If you have not done this yet, you will need to follow the installation guide to get the OS onto that new drive: ROCK: Install Guide

Please let us know where you are in the process, or if you were simply adding a secondary drive for music storage, and we will help you get across the finish line!

Hi Vadim, the system stopped working and I put a new CMOS battery in. Then it seemed the hard drive failed at the same time so I installed a new one.

That is as far as I have got. I tried to install the software via USB prior to installing the new hard drive but that is when you suggested the hard drive needed renewing.

I did this and could not get the Flashed USB to install so took it to a repair shop. They also failed.

So I have a Rev A with new battery, a new SSD for the operating system and the existing storage SSD.

I’ve just tried the ROCK install guide , but as I cannot access the F2 menu nothing happens. I tried to install using the alternative method using F10. On selecting USB as boot I get a message saying

‘Welcome to Grub!’

No other text

Now what, please?

Hello @Julie_Meikle

The “Welcome to GRUB” message is a normal part of the boot process, but it should only appear for a split second. How long does this message stay on your screen? Does the system hang there indefinitely?

If you are seeing this on a brand-new SSD, it usually means the system is attempting to boot from your USB installation drive.

Here is what I recommend as the next steps:

  1. Try a Different USB Drive: We often see issues where the installation hangs or behaves oddly due to a faulty or incompatible USB stick. If possible, try flashing the ROCK image onto a different USB drive.
  2. Prepare the SSD: To ensure there are no conflicting boot records, it’s best if the SSD is completely “unallocated” (no partitions). If you have a way to connect it to another PC and wipe the partitions, that would guarantee a clean slate for the ROCK installer.
  3. Perform a Fresh Install: With a fresh USB drive and a wiped SSD, follow the ROCK installation guide again. In this scenario, the NUC should automatically boot into the installer without you needing to manually trigger anything in the BIOS.

Please let us know if switching the USB drive allows you to move past that GRUB screen!

Thanks.

The grub message stays permanently.

I already tried a different USB and bought this new one as the first one didn’t seem to work.

It is a brand new SSD so I doubt it has any partitions, but I don’t have any way to connect to a PC to try to read it.

I’ll see if a local repair shop can help with that and try again, but it seems that nothing is working. It has been months that it has not worked. I will not throw more money into Roon by buying a new Nucleus as the whole system seems to be very unstable judging by my experience. A help section that is live would be so much more useful than a messaging system that has days in between answers.

Hello @Julie_Meikle

I’m very sorry to hear that the BIOS reconfiguration didn’t resolve the issue and that you’ve run into hardware-related trouble with your Nucleus.

Since replacing the internal components and adjusting the settings hasn’t brought the unit back to life, the best next step is to get in touch with our RMA department directly. They handle all physical Nucleus hardware issues and will be able to advise on repair or replacement options.

To start this process, please open the link below and select ‘Other’ followed by “This issue is related to a physical component”:

Nucleus Troubleshooting Form

They will review your case and help you get sorted out from here. Thank you for your patience throughout the troubleshooting process!

I have used a different USB, checked for partitions, but it still stuck on the welcome to grub page.

I can now access the BIOs (f2) settings and followed the instructions

I have reflashed onto a new usb but still stuck on the grub page

I filled this out but have not heard anything, please can you reply? Thanks
