## Appendix A. Installation Howto 

This document describes how to install Ubuntu 20.04 “Focal Fossa” for the 64-bit ARM (“arm64”). It is a quick walkthrough of the installation process which should contain all the information you will need for most installs. When more information can be useful, we will link to more detailed explanations in other parts of this document. 

## A.1. Booting the installer 

For more information on where to get CDs, see Section 4.1. 

Some installation methods require other images than CD images. The debian-installer home page (http://www.debian.org/devel/debian-installer/) has links to other images. Section 4.2.1 explains how to find images on Ubuntu mirrors. 

The easiest way is probably to download the (CDROM) image, because the files most people need are there on the image. 

The subsections below will give the details about which image(s) you should get for each possible means of installation. 

## A.1.1. Booting from CDROM 

First of all download the image for your architecture and burn it to a CD/DVD. 

## A.1.2. Booting from network 

It’s also possible to boot the Ubuntu installer completely from the net. The various methods to netboot depend on your architecture and netboot setup. The files in netboot/ can be used to netboot the Ubuntu installer. 

## A.2. Installation 

Once the installer starts, you will be greeted with an initial screen. Press Enter to boot, or read the instructions for other boot methods and parameters (see Section 5.3). 

After a while you will be asked to select your language. Use the arrow keys to pick a language and press Enter to continue. Next you’ll be asked to select your country, with the choices including countries where your language is spoken. If it’s not on the short list, a list of all the countries in the world is available. 

You may be asked to confirm your keyboard layout. Choose the default unless you know better. 

Now sit back while the installer detects some of your hardware, and loads the rest of itself from CD, USB, etc. 

Next the installer will try to detect your network hardware and set up networking by DHCP. If you are not on a network or do not have DHCP, you will be given the opportunity to configure the network manually.
