I now use "macOS" to refer to any version of this OS.
Note: As of version 10.12 ("Sierra"), Apple has renamed its OS X OS to macOS. When I refer to "the refind directory" on this page, I mean the directory with that precise name, not the refind- version directory that is its parent. This directory includes a subdirectory called refind that holds the rEFInd binary along with another that holds documentation, as well as miscellaneous files in refind- version itself. Important: A rEFInd zip file, when uncompressed, creates a directory called refind- version, where version is the version number. If you're using Windows, you'll have to install manually. If your Linux system doesn't support these formats, though, or if you're running macOS, using the refind-install script can be a good way to go. For most Linux users, an RPM or Debian package is the best way to go. See the Contents sidebar to the left for links to specific installation procedures.
The details of how you do this depend on your OS and your computer (UEFI-based PC vs. Once you've obtained a rEFInd binary file, as described on the preceding page, you must install it to your computer's EFI System Partition (ESP) (or conceivably to some other location). Mounting the drive(s) in the Rescue Systemįirst, you should determine the partition identifiers of your system by running the command lsblk.Don't be scared by the length of this page! Only portions of this page apply to any given user, and most people can install rEFInd from an RPM or Debian package in a matter of seconds or by using the refind-install script in minute or two. Ifyou restart the server later, the system will boot from the internal drive(s). If you do not reboot your server within 60 minutes after the activation, the scheduled boot of the Rescue System will automatically become inactive. If you want to boot your server to the Rescue System again, you will have to activate it on Robot again. Important note: The activation of the Rescue System is only valid for one boot. You will find this under the Reset tab for the correct server. If you no longer have access to the server, you can use the reset function on Robot. To load the Rescue System, you need to restart the server. Or, if you have already uploaded an SSH key to Robot, you can select the key, and log into the Rescue System without a password.
Now use the password that was given to you when you activated the Rescue System to log in as "root" via SSH. Then pick the correct typeand architecture and activate it.
To do this, click on Servers, select the correct server, and then open the tab Rescue. To start a server in the Rescue System, first, you need to activate it via the the administration interface Robot. Starting the Hetzner Rescue System Activating the Rescue System
Or you can use a KVM Console together with a bootable ISO image of your choice.
Plus, you can install any other software you need using the Rescue System. This makes it possible for you to carry out repairs to the installed system, access the data on the drives, create backups, check the hardware of the server, and to install operating systems. The environment starts using network boot (PXE) and runs in the memory of the server, without touching the drives or your data on them. The Hetzner Rescue System is a Debian based Linux live environment that allows you administrative access to your server, even if the installed system does not boot anymore.
