USB Stick Installs
If you use USB-Sticks as installation media:
Cross-Platform: Ventoy
Ventoy lets you create a multi-ISO bootable USB stick. You install Ventoy once, then simply copy the BlueOnyx ISO (and any other ISOs) onto the drive. No re-flashing is required when you add or update ISOs.
How to Use:
- Download Ventoy from https://www.ventoy.net/en/download.html
- Extract the archive
- Windows: Run Ventoy2Disk.exe
Linux: Run VentoyGUI.x86_64 (or Ventoy2Disk.sh) - Select your USB device carefully
- Click Install (this erases the USB stick)
- After installation, copy the BlueOnyx ISO file onto the Ventoy USB drive
(do not extract the ISO) - Safely eject the stick
Booting:
- Insert the USB stick and boot from it (BIOS/UEFI boot menu)
- In the Ventoy menu, select the BlueOnyx ISO
- The BlueOnyx installer boot menu appears
✔ Works on Legacy BIOS and UEFI systems
✔ Supports multiple ISOs on one stick
✔ BlueOnyx ISOs can be updated by simply replacing or adding the new ISO file
⚠️ Important: Installing Ventoy erases the entire USB stick.
⚠️ On first boot with Secure Boot enabled you may need to enroll the Ventoy key (follow the on-screen MOK enrollment prompts once).
EFI / UEFI Notes
BlueOnyx 5210R, 5211R and 5212R ISO images are hybrid ISOs. They contain both traditional BIOS boot code and a UEFI EFI System Partition image, so they boot on systems with or without EFI.
When you boot a modern BlueOnyx ISO (directly or via Ventoy) on an EFI-enabled machine:
- The firmware loads the UEFI bootloader from the ISO (EFI/BOOT/BOOTX64.EFI / shim + GRUB).
- You get the same BlueOnyx installer menu you see in BIOS mode.
- No special BIOS settings are required beyond selecting the USB device in the boot menu.
- Secure Boot is supported by current BlueOnyx ISOs. If your firmware enforces Secure Boot and the first boot fails, either temporarily disable Secure Boot or (with Ventoy) complete the one-time key enrollment that appears on screen.
Windows only: 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.
