How to Install Arch Linux (Step by Step Guide)

Arch Linux is one of the most powerful and flexible Linux distributions available. Unlike beginner-friendly distros such as Ubuntu or Fedora, Arch follows a minimalist approach, giving users complete control over their system. While this freedom is appealing, installing Arch can be intimidating for newcomers. This step-by-step guide will walk you through the installation process, making it easier to set up Arch Linux on your system.

Why Choose Arch Linux?

Before diving into the installation, it’s important to understand why Arch stands out:

• Minimalist and Flexible – You build the system exactly how you want it.
• Rolling Release – Continuous updates mean you always have the latest software.
• Massive Community & Wiki – Arch Wiki is one of the best resources in the Linux world.
• Performance-Oriented – Lightweight and optimized for your hardware.

If you’re ready for more control over your Linux system, Arch is a great choice.

How to Install Arch Linux Step by Step Guide

Step 1: Download Arch Linux ISO

• Go to the official Arch Linux website and download the latest ISO file.
• Create a bootable USB drive using tools like Rufus (Windows), Etcher, or dd command (Linux).

Step 2: Boot from the USB

• Insert the USB drive and reboot your system.
• Enter BIOS/UEFI settings and set the USB as the primary boot device.
• Once booted, you’ll be greeted with the Arch Linux live environment.

Step 3: Verify Internet Connection

Since Arch relies on online repositories, a working internet connection is required.

• For wired connections, it usually works automatically.
• For Wi-Fi, use:

iwctl

Inside the tool, scan for networks and connect to your Wi-Fi.

Step 4: Update System Clock

Synchronize the system clock with:

timedatectl set-ntp true

Step 5: Partition the Disk

Use fdisk or cfdisk to create partitions. A typical setup includes:

• EFI Partition (512 MB, FAT32, type EFI System)
• Root Partition (rest of the space, ext4 or btrfs)
• (Optional) Swap Partition for better performance

Example using fdisk:

fdisk /dev/sda

Step 6: Format Partitions

Format the partitions you created:

mkfs.fat -F32 /dev/sda1   # EFI partition  
mkfs.ext4 /dev/sda2       # Root partition  
mkswap /dev/sda3          # Swap (if created)  
swapon /dev/sda3  

Step 7: Mount Partitions

Mount the partitions to prepare for installation:

mount /dev/sda2 /mnt  
mkdir /mnt/boot  
mount /dev/sda1 /mnt/boot  

Step 8: Install Base System

Install essential Arch packages:

pacstrap /mnt base linux linux-firmware  

Step 9: Configure the System

Generate the file system table:

genfstab -U /mnt >> /mnt/etc/fstab  

Chroot into the system:

arch-chroot /mnt  

Set time zone:

ln -sf /usr/share/zoneinfo/Region/City /etc/localtime  
hwclock --systohc  

Set localization:

• Edit /etc/locale.gen and uncomment your language (e.g., en_US.UTF-8 UTF-8).
• Generate locales:

locale-gen  

• Set language in /etc/locale.conf:

echo "LANG=en_US.UTF-8" > /etc/locale.conf  

Set hostname:

echo "myarch" > /etc/hostname  

Step 10: Set Root Password

passwd  

Step 11: Install Bootloader

For UEFI systems, install GRUB:

pacman -S grub efibootmgr  
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB  
grub-mkconfig -o /boot/grub/grub.cfg  

Step 12: Create a User

Add a new user and grant sudo access:

useradd -m -G wheel -s /bin/bash username  
passwd username  
pacman -S sudo  
EDITOR=nano visudo   # Uncomment %wheel ALL=(ALL:ALL) ALL  

Step 13: Exit and Reboot

Exit the chroot and unmount partitions:

exit  
umount -R /mnt  
reboot  

Remove the installation USB. Your system should now boot into Arch Linux.

Post-Installation Tips

• Install a desktop environment (GNOME, KDE, XFCE) with pacman -S.
• Add essential tools like networkmanager, pulseaudio, and firefox.
• Enable services with:

systemctl enable NetworkManager
