Running Ubuntu or Debian on the Western Digital WD Sentinel DX4000

• I am now in the process of building a fully solderless installer
• No tools other than USB sticks will be required
• No changes to BIOS options or other reconfigurations required
• SSH install over the network with the current IP shown on LCD

Stay tuned for a complete overhaul for this process!

• Ubuntu is now available
• Work has begun on providing an interface for the entire front panel of the machine, including buttons, LCD (control, contract, brightness) and LEDs. Please visit the dedicated repo for more information and for a working proof of concept: https://github.com/alexhorner/WD-DX4000-IO

Head to Before Install to start!

If this occurs for you, start into Debian/Ubuntu manually and install efibootmgr. Use efibootmgr to delete all boot entried except your Linux installation. Please make sure you check every command you run and have other bootable disks disconnected from the system.

The general command is efibootmgr -b <boot entry> -B but please check this yourself first! To list entries, just run efibootmgr alone. Don't include the asterisks * in the command.

Once complete, reboot back into BIOS and set your boot order as per your OS's install document from this guide.
