June 25, 2025 • 11 min read by admin

Introduction

Arch Linux represents the pinnacle of DIY Linux distributions, offering users complete control over their system at the cost of requiring hands-on configuration. This comprehensive guide will walk you through the entire process, from creating installation media to building a fully functional desktop environment.

Why Choose Arch Linux?

Arch Linux follows a rolling release model and the KISS (Keep It Simple, Stupid) principle. Unlike other distributions that come pre-configured, Arch gives you a minimal base system that you build upon. This approach offers several advantages:

  • Complete Control: You decide exactly what gets installed
  • Learning Experience: Understanding how Linux systems work at a fundamental level
  • Cutting-Edge Software: Access to the latest packages through rolling releases
  • Excellent Documentation: The Arch Wiki is legendary for its thoroughness
  • AUR Support: Access to the Arch User Repository with thousands of additional packages

Prerequisites and Preparation

Before diving into the installation, ensure you have:

  • A computer with UEFI firmware (recommended) or legacy BIOS
  • At least 2GB RAM (4GB+ recommended)
  • 20GB+ storage space
  • Stable internet connection
  • USB drive (4GB minimum) for installation media
  • Another computer for reference (optional but helpful)

Lab 1: Creating Installation Media

Objective: Create a bootable Arch Linux USB drive

Steps:

  1. Download the ISO: # Visit https://archlinux.org/download/ # Download the latest ISO (approximately 800MB) # Verify the integrity using provided checksums
  2. Create bootable USB (Linux/macOS): # Find your USB device lsblk # Replace /dev/sdX with your USB device sudo dd if=archlinux-2024.01.01-x86_64.iso of=/dev/sdX bs=4M status=progress sync
  3. Create bootable USB (Windows):
    • Use Rufus or Etcher
    • Select the Arch ISO
    • Choose your USB drive
    • Use DD mode for compatibility

Verification: Boot from the USB to see the Arch Linux boot menu.

Lab 2: Booting and Initial Setup

Objective: Boot into the Arch installation environment and prepare for installation

Steps:

  1. Boot from USB:
    • Enter BIOS/UEFI settings
    • Disable Secure Boot (if present)
    • Set USB as first boot device
    • Boot from the USB drive
  2. Verify boot mode: # Check if booted in UEFI mode ls /sys/firmware/efi/efivars # If this directory exists, you're in UEFI mode
  3. Set keyboard layout (if needed): # List available layouts localectl list-keymaps # Load your layout (example for German) loadkeys de-latin1
  4. Connect to internet: # For wired connection, it should work automatically ping -c 3 archlinux.org # For WiFi iwctl station wlan0 scan station wlan0 get-networks station wlan0 connect "YourNetworkName" exit

Expected Result: Successfully connected to the internet with ping working.

Lab 3: Disk Partitioning

Objective: Create appropriate partitions for Arch Linux installation

Understanding Partition Schemes:

For UEFI systems, we need:

  • EFI System Partition (ESP): 512MB, FAT32
  • Root partition: Remaining space, ext4
  • Swap partition: Optional, typically 1-2x RAM size

Steps:

  1. Identify your disk: lsblk # Look for your target disk (usually /dev/sda or /dev/nvme0n1)
  2. Partition the disk: # Use gdisk for GPT partitioning (UEFI) gdisk /dev/sda # Commands within gdisk: # o - create new GPT partition table # n - create new partition # # Partition 1: EFI System Partition # First sector: (default) # Last sector: +512M # Type: ef00 # # Partition 2: Root partition # First sector: (default) # Last sector: (default, use remaining space) # Type: 8300 # # w - write changes and exit
  3. Format partitions: # Format EFI partition mkfs.fat -F32 /dev/sda1 # Format root partition mkfs.ext4 /dev/sda2 # Optional: Create and enable swap # mkswap /dev/sda3 # swapon /dev/sda3
  4. Mount filesystems: # Mount root partition mount /dev/sda2 /mnt # Create and mount EFI directory mkdir /mnt/boot mount /dev/sda1 /mnt/boot

Verification: Run lsblk to confirm proper mounting.

Lab 4: Installing the Base System

Objective: Install essential Arch Linux packages

Steps:

  1. Update package database: pacman -Sy
  2. Install base packages: # Install base system, kernel, and essential packages pacstrap /mnt base linux linux-firmware base-devel vim nano networkmanager grub efibootmgrPackage Explanations:
    • base: Minimal package set for Arch Linux
    • linux: Latest Linux kernel
    • linux-firmware: Firmware files for hardware
    • base-devel: Development tools including make, gcc
    • vim/nano: Text editors
    • networkmanager: Network management daemon
    • grub: Bootloader
    • efibootmgr: UEFI boot manager
  3. Generate filesystem table: genfstab -U /mnt >> /mnt/etc/fstab # Verify the generated fstab cat /mnt/etc/fstab

Expected Result: Base system installed in /mnt with proper fstab entries.

Lab 5: System Configuration

Objective: Configure the newly installed system

Steps:

  1. Change root into new system: arch-chroot /mnt
  2. Set timezone: # List available timezones timedatectl list-timezones | grep -i your_region # Set timezone (example) ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime # Generate hardware clock hwclock --systohc
  3. Configure localization: # Edit locale.gen vim /etc/locale.gen # Uncomment your locale (e.g., en_US.UTF-8 UTF-8) # Generate locales locale-gen # Set system locale echo "LANG=en_US.UTF-8" > /etc/locale.conf # Set keyboard layout permanently (if changed earlier) echo "KEYMAP=de-latin1" > /etc/vconsole.conf
  4. Configure hostname: echo "myarch" > /etc/hostname # Edit hosts file vim /etc/hosts # Add these lines: # 127.0.0.1 localhost # ::1 localhost # 127.0.1.1 myarch.localdomain myarch
  5. Set root password: passwd # Enter a strong password

Expected Result: System timezone, locale, hostname, and root password configured.

Lab 6: Bootloader Installation

Objective: Install and configure GRUB bootloader

Steps:

  1. Install GRUB: # For UEFI systems grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB # For BIOS systems (use this instead) # grub-install --target=i386-pc /dev/sda
  2. Generate GRUB configuration: grub-mkconfig -o /boot/grub/grub.cfg
  3. Enable NetworkManager: systemctl enable NetworkManager
  4. Exit chroot and reboot: exit umount -R /mnt reboot

Expected Result: System boots into Arch Linux and you can log in as root.

Part II: Post-Installation Configuration

Lab 7: User Management and Basic Security

Objective: Create a regular user account and configure sudo access

Steps:

  1. Create a user account: # Create user with home directory useradd -m -G wheel -s /bin/bash username # Set password for the user passwd username
  2. Configure sudo access: # Edit sudoers file EDITOR=vim visudo # Uncomment this line: %wheel ALL=(ALL:ALL) ALL
  3. Test sudo access: # Switch to your user su - username # Test sudo sudo pacman -Syu
