Replacing current OS with Ubuntu

Warning: This method will delete your Windows partition. Please make sure you have made a backup of all the data you do not want to loose.

Step 1 (Preparation)

Before starting, download Ubuntu Desktop LTS 20.04 from https://ubuntu.com/#download or get it directly from here. LTS stands for Long Term Support, so this system will be supported for at least the next 5 years without an upgrade to the next version.

You'll get an ISO file, which is a disk image. You need to flash this to a USB drive, using an imager tool. The Raspberry Pi foundation keeps an up-to-date list of imagers for Windows, however, we recommend Etcher. Rufus is another good ISO burner.

In Etcher:

  • Select your ISO file
  • Select your USB drive (plug it in!)
  • Then flash!

Step 2 (Boot)

To boot into the live installation media, plug your USB into your computer/laptop, and reboot - you should be able to boot off it with no problems.

Once boot has finished, you should be presented with the installer!

Installer

Click "Try Ubuntu" to be able to play around with a live preview (or need to use one of the bundled tools to help with installation), otherwise, go direct to "Install Ubuntu".

If you click "Try Ubuntu", you can find the installer later by clicking the icon on the desktop:

Start Installer

Step 3 (Installation)

Select your language

Installer Language

Select your keyboard layout

The auto-detect keyboard should walk you through finding out exactly what layout you have if you're not sure.

Connect to the internet

Choose the wifi you want to connect to:

Wifi

Select software

In most cases you want a "Normal installation" with all the utilities - however, if you're working with less disk space, or want to manually install only the tools you want later, then go with a "Minimal installation".

If you have an internet connection, then select "Download updates" - it makes the install process a little longer, but ensures that everything will be properly up to date.

The "Install third-party software" is slightly more complex. In most cases, you should tick it, and attempt an install - if something breaks and doesn't work, for issues related to drivers, then you can try again, disabling this step, and instead trying to install the drivers and codecs after the install is fully complete.

Installer Software

Choose installation type

Be careful at this step! After you click "Install Now" the install process will begin!

For a pure install, click "Erase disk and install Ubuntu".

Installer Type

At this step, you can also choose to encrypt your disk, by selecting "Advanced features" and selecting both "Use LVM" and "Encrypt the new Ubuntu installation". However, this is optional, and requires you to input your password at each boot.

After you click "Install Now", you'll be asked if you want to proceed with the partitioning layout you've selected:

Installer Partitioning

Verify the changes, and then click "Continue". Note that your partitions will look different depending on your setup.

Select your timezone

Installer Location

Setup your account

You need to pick:

  • Your name (used in the display manager to greet you, etc)
  • Your computer's name (the hostname used on networks, pick something unique and recognizable)
  • Your username (used to login, appears in shell prompts, etc)
  • Your password (standard password guidelines apply, if you want something easy to remember and secure, try diceware)

Installer Account

Wait!

Now just wait for the installer to complete!

Installer Wait

Once it's completed, follow the prompts to shutdown, remove the installation media, and restart your computer. When you startup, you should be booted into Ubuntu!

Now head over to the Post Installation guide to update your system and install some useful software.
