# Install a Linux OS from a template

> Install a Linux OS from a template on a dedicated server using DCImanager, with supported distributions and custom setup options.

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.

> [!NOTE]
>
> 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

**1. Open DCImanager**

In the [Gcore Hosting Portal](https://hosting.gcore.com/billmgr), navigate to **Products/Services** → **Dedicated servers**, select the server, and click **To panel**. DCImanager opens in a new tab.

**2. Open the context menu**

In the server list, click the **...** (three-dot) menu on the right side of the server row. A dropdown appears with available operations.

Click **Install OS from a template**. The installation wizard opens.

**5. Set access credentials**

In the **Access to the server** step, enter a **Server administrator password**. By default, `root` is used as the login.

Optionally, update the **Hostname** and add SSH keys.

Click **Install**. DCImanager begins the OS installation. The server will reboot and come back online with the new OS.
