How to start rebooting a Dedicated Server in rescue mode
Perform the following steps to start your server in rescue mode:
- In the menu bar, under Dedicated Servers, select All servers.
The All Servers Overview page displays.
- Click the Server name / Manage icon for the server that you want to reboot in rescue mode.
The Server Details page displays.
- In the Action menu, click Rescue Mode.
The Choose the rescue image page opens in a new tab:
Select the rescue image you want to boot the server with, GRML or FreeBSD.
If your system is installed with Microsoft (R) Windows(tm) or a Linux distribution you should select "GRML Linux Rescue Image".
If you want to troubleshoot a FreeBSD installation, "FreeBSD Rescue Image" should be selected.
If your server is AMD Sempron or Intel Celeron based, it only supports 32-bit. At this moment starting your server with an amd64 image will result in a failure. Please contact support if you are in this situation.
Optionally, you can:
Provide an SSH public key in the OpenSSH format. This key is placed in the
Uncheck the "Power cycle the server" checkbox. By default a server is power cycled to start rescue mode. If you want to reboot the server yourself, the power cycle can be skipped.

- To start the rescue mode, click the button.
When the rescue mode has launched successfully, you are returned to the Server Details page.
A confirmation message is shown at the top of the page.When the server has fully started Rescue Mode and is reachable, you will receive an email with the details of the IP address and ports that you need to connect to when accessing the server via SSH. After this, root password will be displayed in the Server Management page. The root password is uniquely generated for each Rescue Mode request.
Note: If the password doesn't work and you have not received an email (or callback) yet, it is possible that the credentials displayed are still from an old request.
Additionally, in Rescue Mode the server will generate a new SSH host key, used for the duration of the rescue mode. If you have accessed the server using SSH before, you may receive a warning about host key verification. This is normal.
