# Install a Linux OS from a template

A Linux OS can be installed on a dedicated server by selecting a template in DCImanager. Templates are maintained by Gcore and include the latest supported versions of each distribution.

<Info>
  Windows Server can only be added at the time of ordering a dedicated server and cannot be installed later using this method.

## Reinstall the OS
