Home Assistant OS installation on a Chromebox is reliable but is not as tested as the NUC installation.

When back at the options menu: Exit, and Power Off

Prepare a USB Flash Drive using a PC

Download the latest Ubuntu LTS image file and flash it onto a USB drive (16GB or larger) using Rufus or Balena Etcher. If it's an option, maximize or allow up to 16GB of persistent storage.

Shut down the PC and boot from the USB Drive using the Try Ubuntu option

Once Ubuntu is running, connect to the internet

Open a terminal and install the necessary software:

sudo add-apt-repository universe

sudo apt install libfuse2

Close the terminal and use Firefox to download:

The latest Home Assistant OS Generic x86-64 image from the Home Assistant website. (The same or similar to: https://github.com/home-assistant/o...s/download/9.5/haos_generic-x86-64-9.5.img.xz)
