Debian is a popular, free operating system that uses the Linux kernel. It’s known for its stability and is the basis for many other Linux distributions, including Ubuntu. If you’re looking to install Debian on your computer, this guide will help you through the process step-by-step.
Prerequisites
Before installing Debian, make sure you have the following:
- A computer with an internet connection to download the Debian installation image.
- A USB drive with at least 4 GB of space or a blank DVD.
- Backup of your important data.
Step 1: Download the Debian ISO
Visit the Debian website to download the installation image. You can choose between different types of images according to your needs, such as a live image if you want to try Debian without installing it or a netinst image if you have a good internet connection and wish to download packages during installation.
Step 2: Create a Bootable USB/DVD
Once the ISO file is downloaded, you need to create a bootable USB drive or DVD. You can use tools like Rufus on Windows or the dd command on Linux to create your bootable media.
Step 3: Boot from USB/DVD
Insert your bootable media and restart your computer. You may need to access the BIOS or UEFI settings to change the boot order, making sure your computer boots from the USB or DVD drive.
Step 4: Start the Debian Installer
When Debian starts up, you will see an installation menu. You can choose between the graphical or text-based installer. For beginners, the graphical installer is recommended.
Step 5: Follow the Installation Instructions
The installer will guide you through several steps:
- Select Language: Choose the language for the installation process and for your installed system.
- Select Location: This determines your time zone and local settings.
- Configure the Keyboard: Select your keyboard layout.
- Network Configuration: If you are connected to the internet, the installer will attempt to configure the network using DHCP.
- Set up Users and Passwords: Assign a root password and create a new user account.
- Partition Disks: You can choose to use the entire disk, set up partitions manually, or use LVM. If you’re unsure, opt for the guided use of the entire disk.
- Configure the Package Manager: If you’re using the netinst image, you can select a Debian mirror to download additional software.
- Software Selection: You can choose the environments (like a desktop environment) and utilities you want to install.
- Install the GRUB Bootloader: Make sure to install GRUB on your primary drive so that Debian will boot up when you start your computer.
- Complete Installation: After the installation is complete, remove your installation media and reboot your computer.
Step 6: Post-Installation
After rebooting, you should be greeted by a login prompt or a graphical login screen, depending on the options you chose. Log in with the user account you created during installation.
Update your package index:
sudo apt update
sudo apt upgrade
Install any additional software you require, personalize your environment, and enjoy Debian!
