How to Replace Windows with CentOS: A Comprehensive Guide

Replacing Windows with CentOS involves several critical steps to ensure a smooth and successful transition. Here, we'll walk you through the entire process to help you migrate to CentOS, a powerful and cost-effective open-source operating system.

1. Backup Your Data

Before making any changes, it's crucial to back up all your important files and data. This ensures that you don't lose any essential information during the installation process. Store your backups on an external drive or in a secure cloud storage service.

2. Download CentOS

To begin the installation, visit the official CentOS website and download the latest version of CentOS. Select the appropriate ISO image for your system architecture. For most modern PCs, x86_64 is the commonly used option.

3. Create Installation Media

There are two methods for creating a bootable installation media:

USB Drive: Use tools like Rufus (Windows) or Etcher (cross-platform) to create a bootable USB drive with the downloaded CentOS ISO. DVD: Alternatively, you can burn the ISO file to a DVD if you prefer that method.

4. Prepare for Installation

Ensure your computer is set to boot from the USB drive or DVD. You may need to change the boot order in the BIOS/UEFI settings. To access the BIOS/UEFI setup, press the appropriate key (often F2, F12, ESC, or DEL) during the computer's startup process.

5. Install CentOS

Insert the bootable USB or DVD and restart your computer. You should now see the CentOS installation menu.

Select the CentOS installation option from the boot menu. Follow the on-screen instructions:

Language Selection: Choose your preferred language.

Installation Destination: Select the drive where you want to install CentOS. This will erase any existing data, including Windows.

Partitioning: You can use automatic partitioning or customize it based on your needs.

Network Configuration: Set up your network connection if needed.

Software Selection: Choose the server or desktop version based on your requirements.

6. Complete the Installation

Once you have configured all settings, click on “Begin Installation.” Set up the root password and create a user account if prompted. After the installation is complete, remove the installation media and reboot your system.

7. Post-Installation Setup

After booting into CentOS, you may need to perform some additional configuration:

Update the System: Open a terminal and run: bash sudo dnf update Install Additional Software: Use the package manager to install any additional software you need.

8. Familiarize Yourself with CentOS

Explore the desktop environment if you installed a graphical version or learn basic command-line usage to navigate and use your new operating system effectively.
