In this article, I will explain how to install Ubuntu 18.04.1( Bionic Beaver ) in 5 steps. As you already know Ubuntu 18.04 LTS is the latest stable version of Ubuntu for Desktop PCs and laptops. This version is named as “Bionic Beaver” will be supported by Ubuntu community until April 2013. Please find the new changes and bug fixes in this version from here >>
Before you start, make sure your systems meet following requirements:
- 2 GHz dual core processor or better
- 2 GB system memory
- 25 GB of free hard drive space
I assume you have already have a bootable USB or DVD disk of Ubuntu 18.04.1. If you don’t have one, please download ISO image of the same from here and create one.
Step1: Boot up your installation media contains Ubuntu 18.04.1 – USB or DVD drive:
After DVD drive or USB inserted to your Desktop computer/Laptop, power on your computer and keep pressing F12 on your keyboard until you get Boot Menu. Select USB or DVD drive where you have Ubuntu 18.04.1 installed. After that, you should get something like this on your computer screen.
You can see two options: “TryUbuntu” and “Install Ubuntu”. If you click “Try Ubuntu”, you can boot Ubuntu 18.04.1 LTS from the DVD or USB. But this is not what need here. We need to install Ubuntu on the system so let’s go with “Install Ubuntu”.
Step2: Select Keyboard type and Installation mode:
1. Select a keyboard layout and click Continue. I selected the default one here.
2. As we are installing for Desktop, let’s go with Normal Installation so that you get web browsers, office utilities, media player and all required softwares installed along with the operating system. Click Continue.
Step3: Create Partition table for swap, root and home:
Let’s create partition table for swap, root and home. To do this, select Something else as Installation type and click Continue.
You will see your disk listed in the next windows. You need to create a partition table to proceed further. To do that, Click on New Partition Table. Please note that if you already have a partition created, creating a new one will remove the old partition which means it removes all data in the old partition.
If you are okay with this, proceed further by clicking Continue button on this page.
1. Let’s create swap parition first. Click on the ‘+’ button in the left bottom side and select items from the dropdown as show below.
Size of the Swap partition should be double of your RAM size. If you have 2GB RAM, the swap partition should be atleast 4GB (4096MB). Click on OK after options are selected. Just for your information, Swap space in Linux is used when the amount of physical memory(RAM) is full. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to Swap space and physical memory is freed.
2. Secondly create root parition. Click on the ‘+’ button in the left bottom side and select items from the dropdown as show below.
You can give 40% of your disk space to root partition. It should be atleast 10GB or 20GB. All systems files are stored in root partition. Click OK to continue.
3. Thirdly create Home parition. Click on the ‘+’ button in the left bottom side and select items from the dropdown as show below.
You can give 60% of your disk space to root partition. It should be atleast 10GB or 20GB. All of your user files are stored in this partition. Home parition should be huge because you store all your files there. If the system has multi-users, we have to anticipate that another user may add files to his home directory and that can add up disk space. Let’s be in the safe side and give enough disk space. Click Ok to continue.
Your final partition table should look like this:
Click on Install Now and confirm changes made by clicking Continue button.
Step4: Select Time zone/Location and setup system login:
Select your time zone and Click Continue.
On the next window, please give the computer name, login user name and password. Click Continue.
Step5: Start the Ubuntu 18.04.1 Installation:
Once you click on Continue button in the previous window, installation will start. You will see a page as shown below.
Installation should be completed within few minutes and you would get a page to restart your system.
Click Restart Now. You may remove the USB or DVD drive which you used for installation. Let’s wait for few minutes to boot up our Ubunut 18.04.1 LTS. Fill in the login details once you get the login page. Finally you get Ubuntu 18.04.1 LTS loaded as shown below.
That’s it guys. Enjoy Ubuntu.
