Introduction

The instructions given below will be the pre-install setup. By the end of it, you will have a bootable USB stick with Fedora installed on it.

Distributions

Linux, being a free and open source operating system, comes in several different flavours a.k.a distributions a.k.a distros.
Some of the popular distributions are Ubuntu, Fedora, Arch Linux(btw), etc.
For MCSR, we recommend a distribution based on RHEL called Fedora.
Make sure to go here and download the latest ISO for Fedora.
Click on the ISO file under For Intel and AMD x86_64 systems. This is what we will be using to flash the USB.
You can learn more about Linux Distributions here.

After downloading the distribution ISO from the official Fedora Project website, pick up a USB stick of at least 5GB space or above.
NOTE: The USB stick will be formatted during the install process and all data on it will be erased.
To install the ISO into the USB stick, use Balena Etcher from here. Click on the Windows installer link to download it.
Run through the Balena Etcher installer as per usual.
Plug in the USB stick to your PC and open Balena Etcher.
Under Select Image, locate to wherever you downloaded the Fedora Workstation ISO from before and select it.
Under Select Drive, select the USB device name. It should be auto-selected for you, just make sure its the right USB.
Then click Flash to start creating your Bootable USB!
Wait for it to finish Flashing and Verifying as well. Don't quit Balena until all of it is done.
Congratulations! You just created a bootable Fedora USB!

Make sure to have Secure Boot disabled in your motherboard settings and make sure to have CSM/BIOS mode disabled before you proceed to other sections.
Now we start with the difficult part of the installation. We make decisions based on your PC configuration. So make sure to follow through the instructions very carefully.
