2. Place the bootable media intro the appropriate drive, start-up the machine and instruct the BIOS/UEFI by pressing a special function key (F2, F11, F12) to boot-up from the inserted USB/CD drive.

In a few seconds you will be presented with the first screen of Ubuntu installer. Select your language to perform the installation and hit Enter key to move to the next screen.

7. The installer will load a series of additional components required for the next steps and will automatically configure your network settings in case you have a DHCP server on the LAN.

Because this installation is intended for a server it’s a good idea to setup a static IP address for your network interface.

To do this you can interrupt the automatic network configuration process by pressing on Cancel or once the installer reaches hostname phase you can hit on Go Back and choose to Configure network manually.

10. On this step the installer prompts you to setup a username and a password for your system. This username will be granted by the system with sudo powers, so, technically, this user will be the supreme administrator next to root account (which is disabled by default).

Thus, choose an inspired username, maybe hard to guess for security reasons, with a strong password and hit on Continue. Choose not to encrypt your home directory and press Enter to continue further.

11. Next, the installer will automatically set your clock based on the physical location configured earlier. In case the location is correctly chosen hit on Yes to continue to disk partition layout.

12. On the next step you can choose the method that will be used to slice up your disk. For instance, if you need to create custom partition scheme (such as /home, /var, /boot etc) choose Manual method.

For a general purpose server you can stick to Guided with LVM method as illustrated below, which automatically creates the partitions on your behalf.

Select Partition Method

13. Next, select the disk that will be used by the installer to create partitions and press Enter key.

14. Answer with Yes at the next screen in order to commit changes to disk with LVM scheme and hit on Continue to use the entire disk space for guided partitions.

16. In case your system is behind a proxy or a firewall use the next screen to bypass the network restrictions, otherwise just leave it black and hit on Continue.

17. Next, the installer will configure apt repositories and will install the selected software. After it finishes the installation tasks a new screen will appear which will ask you how to manage the upgrade process. Select No automatic updates for now (you will manually select what updates are necessary) and hit Enter key to continue.
