How to fix "No Bootable Device" error?
If it is not possible to boot the operating system, depending on your operating system you will see the message "No Bootable Device" (eg. MS Windows) or "Booting from Hard Disk ..." (eg. CentOS).
In rare cases, this problem may occur during the installation or reinstallation of the VPS as a result of disconnecting the installation media. Disconnecting the installation media is usually caused by premature interruption of the current installation, eg. by restarting the VPS or also by a very long period of user inactivity before the installation of the operating system on the VPS.
To solve the problem, it is sufficient to click on the "Reinstall" button in the user interface in the detail of the server, which can be found on the "Summary" tab. This will reconnect the installation media. Then complete the operating system installation process over the remote VPS connection.
