Introduction

Ubuntu 18.04 (codenamed Bionic Beaver) is a free, open-source distribution of Linux, based on the Debian operating system. 18.04 is the current LST (long-term support) version which is publically supported until 2023.

In this tutorial, you will learn how to install on Ubuntu 18.04.

5 Installation Steps For Ubuntu 18.04

Step 1: Download Ubuntu 18.04 ISO File

Before you start, make sure you have read the prerequisites, and you have all the recommended system requirements. If you are confident that your system can support the new OS installation, take the first step, and download Ubuntu 18.04.

1. Open a browser of your choice and navigate to Ubuntu’s official download page.

2. You will see two available packages – Ubuntu 18.04 and Ubuntu 19.04. We recommend you opt for the LTS version, as it is more stable.
Select the green Download button and Save to start downloading the package.

3. It will take a couple of minutes to download the .iso file. Once it is done, move on to creating a bootable USB or DVD.

Step 2: Create a Bootable USB

The next step is to create a way to transfer the installation package to your system. You will want your computer to boot from the USB on which the package is on. To do that, you need to create a bootable USB.

This process requires at least a 2GB flash drive and software that creates bootable USB flash drives. There are many options to choose from (Rufus, UUI, UNetbootin, PowerISO, and so on).

For this example, we are going to use Rufus, as it is much faster than the alternatives out there. It is also free and open-source.

1. Download Rufus from the official website. Navigate to the webpage and scroll down to the Download section.

2. You will find a list of the latest updated versions. Today, these include Rufus 3.5 and Rufus 3.5 Portable or other available versions. Click on either one of the first two, choose to Save and then Run the file.

3. A pop-up screen will ask you if you want Rufus to check for application updates online. Click on No.

4. Now, Rufus will open and should appear as in the image below:

5. Insert the USB flash drive. Rufus will automatically detect it as a Device. Set the USB as your device of choice.

6. Next, in the Boot selection, click on the Disk or ISO image option in the drop-down menu and then on select to find the iso file.

7. A new window will pop up in which you need to navigate to the folder in which the Ubuntu 18.04 iso image is located. Select the iso file and click on Open.

Note: You will receive a warning message that all data on the selected USB will be destroyed. If you have important data on it, make sure to transfer it to some other device before this process.


Step 3: Boot from USB

1. Switch off your computer and remove all other USB devices (like printers, memory cards, etc.).

2. Insert the bootable USB and switch on the computer.

3. Next, one of two things will happen:

  • The computer will automatically boot from the USB if our BIOS/UEFI is set up correctly.
  • You need to set up boot from USB manually, through the Boot Menu or BIOS/UEFI.

Boot USB from Boot Menu

As the computer is switching on, you can access the Boot Menu by pressing the correct key (or combination of keys). The keys that take you to the required menu depend on the brand of computer. This is the list of common keys based on the brand:

Asus F8 or Esc
Acer F12, F9 or Esc
Compaq F9 or Esc
Dell F12
eMachines F12
Fujitsu F12
HP F9 or Esc
Lenovo F8, F10 or F12
Samsung F2, F12 or Esc
Toshiba F12

Once you have accessed the Boot Menu, select the USB as the device to boot from and press Enter.
If you are unable to boot from the USB this way, try doing it by opening BIOS/UEFI.

Boot USB from BIOS/UEFI

Just as accessing the Boot Menu, to open the BIOS/EUFI you need to hit the correct keys that correspond to the computer brand. The list of common keys for accessing the BIOS/UEFI is:

Asus F9 or Del
Acer F2, F9 or Del
Compaq F10
Dell F2
eMachines Tab or Del
Fujitsu F2
HP F10, F11 or Esc
Lenovo F1 or F2
Samsung F2
Toshiba F1, F2, F12 or Esc

Once you access the BIOS/UEFI, find the Boot Device Select Menu and set the USB as first in the Boot Order. With this configuration in place, your computer will boot from the USB (if possible). If there is no bootable flash drive present, it will run the OS from the hard drive, as per usual.

Note: Make sure to disable legacy mode or secure boot, if your system has this option.


Note: If you have a dual boot machine, you can set up Ubuntu along with your existing operating system. In this case, you will need to select Something else and create the partitions.


Step 4: Run Ubuntu

When you have successfully managed to boot the system from the USB, a Welcome screen will appear as in the following image:

welcome screen, try ubuntu or install ubuntu

The welcome screen offers you two options:

  1. Try Ubuntu directly from the CD, without installing
  2. Install Ubuntu

Step 5: Install Ubuntu

1. To install Ubuntu 18.04, click the Install Ubuntu button and an installation wizard will appear.

2. First, choose a language for the keyboard layout and click on Continue. In this example, we opted for English.

3. Next, select whether you want the Normal or Minimal installation. The difference is the number of apps it includes.

Also, you can choose if you want the system to Download updates while installing Ubuntu (which is recommended) and Install third-party software (optional).

Once you have decided, click on Continue.

select type of installation

4. The wizard will ask you what kind of installation type you want to perform.

If you have backed up all your data, we recommend choosing to Erase disk and install Ubuntu. Again, be aware that this will delete all data on your underlying operating system.

Finish by clicking on Install Now.

Note: If you have a dual boot machine, you can set up Ubuntu along with your existing operating system. In this case, you will select Something else and create the partitions.


5. A pop-up window will inform you what kind of changes it will make to your disk. Click on Continue to agree to the changes and erase any existing software on your drive.

6. Next, it will ask you for your location (time zone). Select the appropriate one and press Continue. Or read our tutorial on setting the Timezone, Date, and Time on Ubuntu.

7. In the next section, type in the required information, such as username and password for the root user. Then, hit Continue.

8. With this, the official installation begins.
