Installing Ubuntu Server 22 on an Old Laptop

Introduction:
Ubuntu Server 22 is a free, open-source operating system suited for various server applications. Through the book, we will set up a server (laptop or desktop) that you can access and hook up to a remote server on AWS. While you can most likely learn and apply all the concepts without a server in your home, I believe it will be a disservice if you choose not to build one. However, the rule is that you should think no differently between the two. Like R and Python, they are the same thing.

Prerequisites:

Step-by-step Installation Guide:

Preparatory Steps:

  1. Download the ISO:
    Begin by obtaining the Ubuntu Server 22 LTS.

  2. Make the Bootable Drive:
    For a comprehensive guide on preparing a bootable Ubuntu thumb drive, refer to the official Ubuntu tutorial.

Installation Process:

  1. Accessing the BIOS/UEFI Settings:
    With the thumb drive prepared, insert it into your old laptop. Restart the laptop and, upon booting, repeatedly press the designated key (commonly F2, F10, F12, DEL, or ESC) to enter the BIOS/UEFI settings. The specific key may vary based on your laptop’s brand and model.

  2. Adjust the Boot Sequence:
    In the BIOS/UEFI menu, navigate to the boot order settings. Prioritize the USB drive as the primary boot device. Save your changes and exit the BIOS/UEFI.

  3. Launch the Installer:
    On restarting, the laptop will boot from the USB drive, initiating the Ubuntu Server 22 installation process. Accept the defaults if you are unsure. If you mess up anywhere, blow it up again. You can’t break anything if you aren’t concerned about data on the device.

  4. Connect to WiFi During Installation:
    One of the vital steps during installation is network configuration. Ensure you connect to WiFi when prompted. Ubuntu Server 22 has streamlined this process, allowing for automatic WiFi configuration. This step is important since setting up WiFi post-installation on the server can be considerably more intricate without an initial connection. If you don’t want to set up wifi, you can grab an Ethernet cable and plug the laptop onto your router directly. You will still be able to access it through WiFi.
