You can install Ubuntu inside a virtualbox in Windows
You can use Bash on Windows feature to install it inside Windows
You can dual boot Ubuntu with Windows (so that you can choose which OS to use at the time your system boots)
You can replace Windows with Ubuntu by wiping it altogether from your system
The method I am going to show in this tutorial is the fourth one. You wipe out the entire system and let Ubuntu be your only operating system. In my experience, this is the easiest way to install Ubuntu.
The procedure shown here works for Ubuntu and all other distributions based on it such as Kubuntu, Xubuntu, Lubuntu, Ubuntu Budgie, Linux Mint, Linux Lite etc. The screenshot might look a little bit different but the steps are basically the same.
Install Ubuntu by replacing Windows and other operating systems
What do you need in order to install Ubuntu:
A USB of at least 4 GB in size. You can also use a DVD.
Internet connection (for downloading Ubuntu and live-USB making tool, not required for installing Ubuntu)
Optionally, you may need an external USB disk for making a backup of your important data (if any) present on the current system
If you are going to install the default Ubuntu GNOME, the system requirements are:
A system with 2 GHz dual core processor or better
4 GB of RAM or more
At least 25 GB of hard disk space
Step 1: Download Ubuntu to How to install ubuntu
Before you do anything, you have to download Ubuntu. It is available as a single ISO file of around 2 GB in size. An ISO file is basically an image of disc and you need to extract this ISO on a USB disk or DVD.
Step 2: Create a live USB
Once you have downloaded Ubuntu’s ISO file, the next step is to create a live USB of Ubuntu.
A live USB basically allows you to boot into Ubuntu from a USB drive. You can test Ubuntu without even installing it on your system. The same live USB also allows you to install Ubuntu.
There are various free tools available for making a live USB of Ubuntu such as Etcher, Rufus, Unetbootin, Universal USB installer.
You can follow this tutorial to learn to make live USB of Ubuntu with Universal USB Installer in Windows.
Step 3: Boot from the live USB
Plug in your live Ubuntu USB disk to the system.
Now, you need to make sure that your system boots from the USB disk instead of the hard disk. You can do that by moving the USB up in the boot order.
Restart your system. When you see a logo of your computer manufacturer (Dell, Acer, Lenovo etc), press F2 or F10 or F12 to access the BIOS settings.
Now, the BIOS screen could look different for your computer.
Step 4: Install Ubuntu
Now you should boot into the live Ubuntu environment. You’ll the grub screen that gives you the option to either try Ubuntu without installing or install it right away.
