# Graphical installation Now that your YunoHost install medium, you can start with the installation. ## 1. Plug the network cable If you want the network configuration to be set up automatically, you have to plug your server with an **Ethernet** cable **right behind your main router**. The wireless connections are not supported yet, and if you use intermediate routers, the network ports opening will not be automatic: Your server will not be accessible externally. ## 2. Boot on CD / USB key Boot up your server with the USB key or a CD-ROM inserted, and select it as **bootable device** by pressing one of the following keys (hardware specific): ``````, ``````, ``````, ``````, `````` or `````` ## 3. Launch graphical installation You should see a screen like this: * Select `Graphical install` * Select your language, your location and your keyboard layout * If a partitioning screen appears, confirm.
Caution: This will totally erase the data on your hard drive
* Let the installer do the rest, it will download required packages and install them.
If it fails, you probably have an Internet connection issue. Check that your computer is physically connected and retry.
* It should reboot automatically. ## 4. Proceed to post-installation Once booted, your computer should display a screen like this: You can proceed to post-installation right away, or access the **IP** address shown on this screen from another computer's web browser (usually `http://192.168.x.x`) If you encounter this kind of error, click on "**Proceed**" or "**Add an exception**". This means that you have to trust the certificate which secures your server's connections. Since this is your server, you can bypass it serenely here :-)
