Once the system is fully booted from Live USB or CD, you will get an installer screen like below.
For installing the Ubuntu 18.04, click on the Install Ubuntu.
Select your keyboard layout. If you are not sure, use the Detect Keyboard Layout option. You can also test your selection by typing in the test text box.
On this screen, you need to select the apps for installation.
Normal Installation – If you select this option, you will get a graphical desktop environment with all regular software.
Minimal Installation – If you select this option, you will get a basic desktop environment with a browser and core system administration utilities.
You can either choose to install updates and other third-party software while installing Ubuntu 18.04 or leave as it is.
The updates and third-party software installation requires internet and installation may take an hour-long depends on the downloadable contents.
For this demo, I chose Ubuntu Normal installation without any updates and third-party software.
Step 5. Create Partitions
Next is the installation type, this installation on the fresh HDD. So, I have only two option in the installation type. Depends on the other OS on your HDD you will get more options.
Please choose any one of the methods.
5a. Automatic Partitioning
Erase disk and install Ubuntu – The installer will format the entire hard drive and install the OS. The Ubuntu installer will take care of creating the required partitions for OS installation. Use this option if you don’t mind about partition layout and its size. Click Install Now.
Once you clicked Install Now, the installer will ask you to confirm the auto partitioning. Click on Continue.
5b. Manual Partitioning
Something else – Use this advanced option, if you want to create partitions manually with the custom size. Click the Continue button.
In this page, the installer will list all the available hard disks. In my case, I have only one hard disk with the size of 100GB. Since this is a new disk, you must click on New Partition Table to create an empty partition.
Pop up will ask you to confirm the creation of empty partition table. Click on Continue.
We will now create three partitions. Partition details are shown below:
/boot – 500MB
swap – 4098MB (2*RAM)
/ – Remaining (95GB)
Select the free space and then click on the + sign at the bottom to create a partition.
Following shows for /boot partition.
Following screen shows for the swap partition. It is recommended to have the swap partition twice the size of the physical memory. If your system has enough memory, then you can choose not to have a swap partition.
Following is for / (root) partition. We will use the remaining space for / partition.
Review your partition layout and click on Install Now.
Write the changes to disk by clicking on Continue.
Step 6: Additional Configurations
Select your location from the map and then click Continue.
In this screen, you can create a username and password for the system. Also, set the hostname for your system.
Here is one thing you should remember – if you select Login automatically, then the system will directly take you to desktop without asking any credentials.
It’s best if you set a very secure password for your the user. Once it’s done, click on Continue.
Step 7: Ubuntu 18.04 – Installation

The installation will take at least 25 to 30 minutes. Once the installation is over, click on Restart Now.
