A tool to write the ISO to the USB stick, such as balenaEtcher or Rufus.

After writing the ISO to the USB stick, boot the computer from it and choose Try or Install Ubuntu MATE. When the desktop appears, double-click Install Ubuntu MATE 24.04 LTS to start the installer, then follow the steps below.
