The Linux Rescue System allows you to access your server to diagnose and repair a damaged system and/or install a new Linux Operating System (OS) on your hard drive(s) quickly and conveniently.

The Linux Rescue System boots and runs entirely from the network -- no installation, configuration or setup functions required. By activating the Rescue System, you are able to boot and run your Self-Managed server using a minimal Linux Operating System (OS) through the Hetzner network. In other words, your server’s hard drive is not required to boot into the Rescue Operating System.

Once you have completed the necessary repairs, you will need to boot your server with your original or newly installed OS using your server’s hard drive as before.

For example: If your server’s boot loader configuration contains failures, you can use the Rescue System to repair it and rewrite the boot loader.

To activate the Linux Rescue System:

  1. Browse to konsoleH and log in at Admin level
  2. Select or search for your Self-Managed server in the Hosting Service tab
  3. Select Rescue System from the left-hand menu.kh-rescue-system1
  4. Select 64bit Linux Rescue System
  5. Click on Activate in the top right-hand corner.kh-rescue-system2
  6. A randomly generated password will be allocated to you to access the Rescue System. (Copy the password immediately). kh-rescue-system3
  7. Reboot within 5 minutes to enter the Rescue System. The Rescue System will automatically deactivate after 5 minutes if you have not rebooted.
