Installation of CentOS

The installation of CentOS is divided into three main parts below are the steps:

• ISO Download
• Preparing a bootable USB
• Final Setup

1. ISO Download

Before we begin the installation process, we need to download the ISO file for CentOS. For that, all the versions of CentOS are available on the official site centos.org. 

Step 1: Go to the CentOS website and go to the downloads tab.

Step 2: Click on the correct ISO file for your system architecture (most likely x86_64 for modern systems).

Step 3: Choose a mirror to download the ISO from (preferably from mirrors in your region for better download speeds).

Step 4: Download the version that says DVD-2009.iso

2. Preparing a bootable USB

Step 1: Now, Connect the USB flash drive to your system.

Step 2: Use a tool like an etcher or UNetbootin, etc to flash the drive.

Note: To enter the BIOS a special hotkey is required, this key can differ from manufacturer to manufacturer and model to model. For example, the hp laptop uses F10 and ESC keys as its primary hotkeys for the step.

3. Final setup

Step 1: Click on the option "Install CentOS 7" and wait till Graphical Interface appears.

Step 2: Choose your installation language. Here, we have chosen English.

Step 3: Configure options such as date and time, network configuration, etc.

Step 4: Choose the software to be installed depending on the use case and familiarity with the desktop.
