Rescue system is basically a temporary Linux operating system which. The first step is to log into your Hetzner robot, after logging into Robot. However, you first need to reset the server before the rescue system is installed. Please help me to install Windows OS On Hetzner Server, show me a guide how can i install Winddows OS through Hetzners Rescue System.

installimage Script
The installimage script provided by Hetzner offers an easy and fast method of installing various Linux distributions.
Installimage can be run directly from the Rescue System on your server. It offers a menu driven interface where you can select a Linux distribution of your choice. You have full control over the partitioning of your drive(s) and can activate the use of sofware RAID as well as LVM using a simple editor.
![]() Running installimage
To use installimage you first need to activate and then boot into the Rescue System.
Once logged into the Rescue System as 'root' using the password displayed in the Robot, type 'installimage' to start the installimage script:
The following menu will be shown:
After choosing an image, you will receive a note that the editor will be started, which opens the configuration file.
Midnight Commander ('mcedit') is used as editor.
OS Choices
We offer a number of standard images that you can use. These are typically the latest version of the particular distribution.
Advanced users can also install older versions of these distributions, by going to the 'old_images' folder. Please note that we don't offer any support for these older images.
In addition, advanced users can also create their own OS images and install them. Please check the guide on how to install your own OS images for information on how this is possible and for a list of the requirements.
autosetup
If installimage finds an /autosetup file in the Rescue System, it will automatically use this as the configuration file. No menu and no editor are displayed unless there are errors in the file.
Variables
The following variables can be adjusted to customize the installation.
Drives
The drives that are present in the server are identified in the first row with the variable DRIVE. Above each line you can see the type of drive.
Here you can select on which drives you want the OS to be installed. The drives will be completely wiped, and all data currently on them will be lost.
If you want to leave a drive in its current state and not make any changes to it you can leave it out (remove it) by placing a '#' before it. Please note that doing so means that the number after the next DRIVE variable must be properly adjusted.
Example:
SWRAID
When the server has multiple drives the variables 'SWRAID' and 'SWRAIDLEVEL' can be used to create different software RAID levels. Any software RAID levels are always applied to all (marked with DRIVE, as discussed above) drives. If you don't want a software RAID on a particular drive, you'll need to remove it accordingly.
The script can create software RAID with levels 0, 1, 5, 6 or 10.
Bootloader
The bootloader Grub is pre-configured (in the past we also offered Lilo). Depending on the operating system GRUB2 or GRUB1 (legacy Grub) is installed.
Hostname
The variable 'HOSTNAME' sets the corresponding host name in the system.
Partitions / File systems
The installimage also supports the adjustment of the partitioning scheme (including the use of LVM). The designated syntax can be found in the examples in the editor.
Operating System Image
This is the full path to the operating system image, and only needs to be specified if a custom image is being installed.
Installation
After leaving the editor with F10 (save and quit), the syntax of the config file is checked. Should it contain errors, you will be returned to the editor.
If you see this output after 1-5 minutes (depends on the image and partitioning used), the system is ready and bootable.
The root password is set to the current password of the Rescue System.
After a 'reboot' in the Rescue System
the newly installed system is booted and you can login with the previous Rescue System password.
Particularities
When installing Debian or Ubuntu using the installimage script, the times for the cronjob in /etc/cron.d/mdadm are set randomly.
Frequently Asked QuestionsWhy can't I create partitions larger than 2 TiB?
The creation of partitions larger than 2TiB is only possible with a GUID Partition table (GPT). Thus only operating systems which include GRUB2 that supports booting from GPT drives can be installed
The installation script shows one or more errors. What should I do?
Re-run the installation. Should you get the same error again, please send the complete screen output and the contents of the file /root/debug.txt to [email protected].
Do I have to put 'all' at the end of the partition table or can I put this line further at the top?
The size 'all' in the config file means use the rest of the available space on the drive. Since partitions are created one after another, the partition table will end after using 'all' because there will be no space available afterwards. Of course, it is also possible not to use 'all' at all.
Pressing F10 does not work. Instead '~21' (or something similar) is displayed.
Press Escape and then '0'. In most cases this has the same effect as F10.
Who is the author of the script? Can I use it freely?
The scripts were written by developers of Hetzner Online GmbH and are maintained and extended by them. The scripts are written in bash and are available in the rescue system. They can be used and modified freely. Hetzner Online GmbH assumes no liability for any damage caused by changing the scripts and excludes any support for guides that include changes to the script.
What is the MySQL Root password when LAMP has been installed?
The MySQL Root password on a LAMP Image can be found in the /password.txt file.

Table of Contents.It has been a long time since I’ve written an article. Recently I was working with a client, and the client lost his root password.
The server was hosted with Hetzner. In this article, we are going to see that how we can reset the root password if it is somehow lost. You need to have access to Hetzner robot to reset server root password from the rescue system. What is a rescue system?Let see what is a rescue system, because sometimes people don’t really know what actually rescue system is and why it is used. Rescue system is basically a temporary Linux operating system which runs on the server itself (Inside server ram). It is most used when you have some trouble in your main operating system and something is not working, the good example is losing a root password.Or if your filesystem on the main operating system does not work.
There can be various possible reasons that you might need to boot into the rescue system of your server. In this article, we will see that how we can use rescue system to reset root password of the server, there are various possible configurations of your hard disk that you might have used and each may require a different procedure to reset the root password:-. OS is installed with Raid. OS is installed on LVM. OS is installed on simple disk partitions.We will see for different disk configurations that how we can reset the password. Step 1: Activate the Rescue System!The first step is to log into your Hetzner robot, after logging into Robot you will see something like this:On the left side, you will see the menu, you need to click on “Servers”, and you will see the list of servers on the right side.
Just like you see in the image above. Currently, I’ve 2 servers in the list, I need to choose one of them to activate the rescue system. Once the server is selected you will have to follow the steps mentioned below:.
First, click “Rescue” from the menu. Second, you have to choose the operating system to be installed as a rescue, leave the defaults.
Finally, click “Activate rescue system”.After you click “Activate rescue system”, it will provide you with the password that you can use to log into the rescue system. However, you first need to reset the server before the rescue system is installed.Resetting the server is very simple, just click the headings by following the sequence in the above screenshot and your server is ready to be used. Once the reset is successfully you can log in to rescue system and start resetting your password. Step 2: Mount the hard drives of your server!The second step of this process is to mount your hard drives because you need to access your installed operating system to reset the root password. As I’ve discussed above there can be many ways your server might be configured, let see how we can mount the root file system of the server to reset root password in each configuration.
Server Disks with no RaidIf your server has 1 or multiple disks but no Raid or LVM, it is possible that OS can be installed on either of them. You can list your disks using the following command. Mount / dev / sda2 part2Commands above will mount the detected partitions on the directories we created above.
Now you can see these folders to check which one have your operating system installed. Once you are certain that your OS is installed on /dev/sda2 you can start resetting your password.
But before resetting the root password, let see how we can mount drives with other disk configurations. Server Disks with RaidIf your server has disks with Raid, then mounting the drives is bit different. So be careful about your disk configurations before you start mounting them. You can list your MD devices using. Mount / dev / mapper / vg0 - root lvm2Well, in this case, the logical volume with “root” in its name gives you a hint that OS is installed on this logical volume, however, you can still mount all logical volumes and manually check. Step 3: Reset the passwordUntil now we’ve only prepared to reset the root password, in Step 2 we saw that how we can mount our server disks so that we can reset our root password.
Without mounting the server’s disks we can not reset the root password, so please carefully read the step 2.Note: Please note that on step 3, I’ve mentioned 3 ways to mount the server disks, however only one would apply to your server depending upon how its disks were configured when the operating system was installed.Once the disks are mounted and you are sure about which disk your OS is installed, you can easily reset the root password. We will assume that your operating system disk is mounted at “osmountpoint” folder in your current working directory. Keeping in mind this information we can use commands below to reset the root password.
