ROCK
For those running ROCK, you’ll want to download the latest version here and run the recovery function . Note that if you install instead of recover, your database and settings will be lost, so it’s important you choose the correct option.

Option 1: Windows / Mac OS / Linux
- Plug in your USB flash drive (it must be larger than the factory reset image size – 1GB is more than enough).
- Download and install Etcher from https://etcher.io/
- Start Etcher
- From the Etcher application interface, select your
.img.gz
file as “the image” - From the Etcher application interface, select your USB flash drive as “the drive”
- Click on “Flash!”
Installing
- Turn off your NUC.
- Unplug any USB storage you might have plugged into it. You can plug it back in after your install.
- Insert the USB flash drive you prepared earlier into the front of the NUC
- Turn on the NUC and press the F10 key on your keyboard. Continue to hold the F10 key down until you appear at a menu that is asking you which device you’d like to boot from.
- Select the USB flash drive.
- Follow the instructions to install Roon OS. This procedure can take a few minutes, depending on the performance of your USB flash drive and the SSD to which you are installing.
- Once it is done installing, unplug the USB flash drive and hit ENTER to reboot.
- On next boot, don’t hold F10. Your NUC should boot from the SSD, and a few seconds later, you should see a Roon message displaying the IP address of the NUC. This IP address should be entered in a web browser (on another computer) in order to complete ROCK setup (installing Codecs).
