Install Ubuntu Desktop 18.04 LTS on a PC with existing windows 10 and linux

This tutorial will show you the simple steps of installing a modern Linux Distribution – Ubuntu Desktop 18.04 LTS. Here we present the more advanced setup installation, when you have already had installed operating systems, so this installation will add Ubuntu 18.04 LTS to our two existing ones – Microsoft Windows 10 Professional and Fedora Workstation 28. So we have 3 hard disks – one is NVME, the other two are SSDs and we want to install our Ubuntu 18.04 to the first disk – “sda” in this case. Our first SSD has two partitions, which we will remove and make new disk layout for the Ubuntu installation with three partitions.
Ubuntu Desktop 18.04 LTS comes with the following software:

  • Xorg X server – 1.19.6
  • GNOME (the GUI) – 3.28.1
  • linux kernel – 4.15.0
  • linux-firmware – 1.173
  • QT – 5.9.5
  • libc – 2.27
