How To Dual Boot Ubuntu 20.04 LTS And Windows 10

Introduction

 
The first thing for this tutorial is that you need to know what an operating system is. An operating system acts as an interface between a user and computer hardware. As per Wikipedia, "An operating system is system software that manages computer hardware, software, and handles various services for computer programs". We know that Microsoft Windows is a family of proprietary operating systems designed by Microsoft Corporation.
 
Like Windows or Mac OS, Linux is also an operating system. Linux is a family of open-source Unix-like operating systems. Some of the popular Linux distributions include Debian, Fedora, Linux Mint and Ubuntu.
 
Ubuntu is a free and open-source Linux distribution based on Debian. As per Wikipedia, "Ubuntu is released every six months, with long-term support (LTS) releases every two years. As of 23 April 2020, the latest release and also the most recent long-term support release is 20.04, which is supported until 2025 under public support and until 2030 as a paid option".
 
There are some benefits of using Ubuntu — it's free (I think this is the most attractive feature), fully customizable, more secure, open-source, and command-line based.
 
This tutorial will show you various steps on how to dual boot Ubuntu 20.04 LTS and Windows 10.

Creating a Partition For Ubuntu

 
Since you are going to install the Ubuntu along with Windows 10 operating system. Then, you have to create a free partition (unallocated space) in your system to install the Ubuntu on it. To create a free unallocated space in your system, you need to shrink the existing drive or volume that you want. Follow the below instructions to proceed.
 
Step 1
 
From the Start menu, open the Run dialog box. (Alternatively, you can Press the "Window + R" key to open the RUN window).
 
Step 2
 
Type "diskmgmt.msc" and press enter to open it.
 
Step 3
  
To shrink the particular disk partition that you want, select it and then right-click on it and select "shrink volume".
 
Step 4
 
After clicking the "Shrink Volume" option, a "Shrink E:" window will appear on the screen. Just enter how much space you want to shrink in MB and click on the Shrink button. For example: If you want to shrink 60 GB, select 61440 MB in "Enter the amount of space to shrink to MB". 
 
Step 5
 
After completion of the shrinking process, you will see a new Unallocated space which can be used as a new partition or volume.
