This will take you to the Ubuntu server installation menu, where you can select the language, keyboard layout, and other installation options. Follow the prompts to complete the installation.
Step 3: Configure Network Settings
After installation, you will need to configure your network settings, including IP address, netmask, gateway, and DNS.
