This tutorial explains how to install Ubuntu 18.10 for beginners with an additional guide for computers with UEFI. This tutorial is applicable to all Official Flavors too (such as Kubuntu, Lubuntu, etc.) as the steps are actually not different. You will prepare two blank partitions first, then follow ten steps of installation. For systems with UEFI, like most laptops sold after 2010, you will need to create a 200MB EFI Partition. Anyway, enjoy Ubuntu 18.10, happy installing!

  • Make bootable USB by writing the ISO image with program like Disk Utility (GNU/Linux), Rufus (Windows), or Disk Utility (macOS).
  • Create two blank partition, first blank >=20GB, and second blank 1GB. First one will be your main partition, and second one will be swap.
  • If your computer uses UEFI (new generation BIOS), create third blank partition of 200MB. This will be your EFI Partition later.

Booting & Enter Live Session

Boot your bootable USB drive so your computer shows Ubuntu 18.10 welcome screen. You will be asked either to enter Try Ubuntu (LiveCD) or Install Ubuntu. Choose Try Ubuntu.

Start The Installer

On the desktop, double-click the Install Ubuntu icon. This will start the operating system installer (it's called Ubiquity).

1. Select Language

Choose English. Other language is your choice, but the rest of this article uses English anyway.

2. Select Keyboard Layout

Select default choice (EN-US) unless you are using special charset like Japanese, Arabic, etc.

2. Select No Internet

Choose "I don't want to connect" here. The installation will be quicker this way.

3. Select Normal Install

Choose "Normal Installation" only and continue.

4. Select Something Else

On the Installation Type stage, choose "Something Else", leave other options. This will bring you full control disk partitioner.

5. Create Main Partition

If your computer has UEFI, first follow Special Step for UEFI below.

Now you are in the disk partitioner. Create your main partition from the first blank:
  • Select your first blank partition
  • Press Change
  • Fill Use as: Ext4 Journaling Filesystem
  • Give check mark to Format the partition
  • Fill Mount point: /
  • OK
  • Let it creates the partition

Special Step For UEFI

Be sure that you already have third blank partition of 200MB.
  • Select that 200MB partition.
  • Press Change.
  • Choose Use as: EFI Partition
  • OK
  • At this point, you should have a partition called "EFI" there
  • Go back to Step 5 above

6. Create Swap Partition

Same as previous step, except here you choose Use as: swap area and format it.

7. Place the Bootloader

On the bootloader location selection, choose the same address as your hard disk address. Here, for example, as my hard disk is /dev/sda so I place my bootloader in /dev/sda too. The correct location for a bootloader is the same disk where your main partition is located.

8. Start the Installation

Press Install Now to begin the real installation. Please read carefully on the summary showing as this is your last chance to revert back if you find any wrong choice. Be sure once again. And if you are sure, Continue.

9. Provide Personal Information

Here you will choose your geolocation (to determine your time, currency, measurement units) and create your username+password.

Choose your country or region (this is changeable after installation)

Create your own username & password

10. Wait

You just need to wait the installation process for +/-15 minutes. On an SSD system, it takes no more than 12 minutes. During the progress, you will see beautiful slideshow introducing Ubuntu 18.10 like this.


Once finished, the installer says you can Restart Now. Restart and enjoy Ubuntu 18.10.
