5210R/5211R/5212R: Installation media updated

07Jan 2026Posted by: mstauberCategory: General

We just published new BlueOnyx 5210R, 5211R and 5212R installation media that includes all updates as of today. 

  • New ISO images
  • New Incus/LXC Container images

These can be downloaded from the usual locations mentioned here.

The new ISO images contain all DNF updates as of today and have been rolled up in a new fashion to make them more resilient and robust if "burned" to USB sticks. Our ISOs have some important characteristics:

  • They are hybrid ISOs (BIOS + UEFI)
  • They use Anaconda’s modern layout
  • The installer expects a proper block-level write
  • Some USB tools require special mode selection
  • Always choose "DD mode", "Raw mode", or "Image mode" when offered to deploy them to USB sticks for installation on your servers.

If you use USB-Sticks as installation media:

Windows: Use Rufus

Rufus is a popular Windows USB creation tool, but requires correct settings for BlueOnyx.

Required Settings:

  • Select your USB device
  • Select the BlueOnyx ISO
  • Boot selection: ISO Image
  • Partition scheme: GPT (recommended for UEFI systems), MBR (legacy BIOS), Target system: UEFI (recommended)

When prompted:

❗ Select "Write in DD Image mode"
⚠️ Do NOT use ISO mode. ISO mode will produce a USB that boots but fails during installation.

Cross-Platform: balenaEtcher

balenaEtcher works on Linux, Windows, and macOS and is beginner-friendly.

How to Use:

  • Select the BlueOnyx ISO
  • Select the USB device
  • Click Flash
    ✔ Etcher automatically uses raw image mode
    ✔ Fully compatible with BlueOnyx ISOs
    ✔ No manual options needed
