Arch Linux Installation for Beginners

A concise, step‑by‑step guide.

Target: sdY/nvmeY drive FS: Ext4 Boot: UEFI

1 - Download & verify ISO

Download the latest ISO from archlinux.org. Verify it with the official checksum.

sha256sum archlinux-2025.05.01-x86_64.iso

Tip: Ensure the hash matches the one published on the website.

2 - Create installer USB

On Linux, find your device with lsblk and write the ISO with dd. On Windows, use Rufus.

Linux

lsblk
sudo dd if=archlinux-2025.05.01-x86_64.iso of=/dev/sdX status=progress bs=4M conv=fsync

Replace /dev/sdX with your installer USB device.

Warning: Make sure that your USB drives do not contain any important data.

Windows

Use Rufus to write the ISO to your USB drive.

3 - Connect to the Internet

Now plug in the USB installer

This next step is only necessary if you are using a Wi-Fi connection. If you are using Ethernet, you can skip it.

Let’s connect to the internet using iwctl:

  1. Detect any Wi-Fi adapters:
  2. iwctl device list

    You should see a wireless interface (e.g., wlan0 or similar).

  3. Scan for nearby networks:
  4. iwctl station wlan0 scan
  5. List available networks:
  6. iwctl station wlan0 get-networks
  7. Connect to your Wi-Fi:
  8. iwctl station wlan0 connect SSID

    Replace SSID with your Wi-Fi network name, press ENTER, type your passphrase, and exit iwctl with exit.

  9. Test your connection:
  10. ping -c3 archlinux.org

4 - Partition target Drive

Tip: To have the best partition layout, it’s recommended to create a separate home partition. This way, if you ever mess up the root partition, you can reinstall the system and mount the existing home partition without losing your personal data.

The general guideline is: the more disk space you have, the better it is to have a separate home partition. I recommend giving your root partition about 25% of the total disk space and leaving the rest for the home partition. This will result in three partitions: EFI, ROOT, HOME.

Example for a 512 GiB Drive

  • EFI partition: 2 GiB
  • Root partition: 128 GiB (25%)
  • Home partition: 382 GiB (remaining space)

As for swap, it’s better to create a swap file instead of a dedicated swap partition. This makes resizing easier. The size of the swap file depends on your RAM and whether you want to enable hibernation. For instance, if you have 16 GiB of RAM, a 16 GiB swap file is a reasonable choice.

Create two partitions on the target Drive (512GiB):

#PurposeSizeType / FSMount
1UEFI system2 GiBvfat (FAT32)/boot
2Root128 GiB (25%)Ext4/
3HomeRestExt4/home
cfdisk /dev/sdY

After opening the target drive with cfdisk, you need to create two partitions: an EFI partition and a root partition.

Warning: Double‑check the target device (e.g. /dev/sdY) with lsblk to avoid wiping the wrong disk.

5 - Create Filesystems

Now that the partitions are ready, we need to format them with appropriate filesystems.

mkfs.vfat -F32 /dev/sdY1

Formats the first partition as FAT32. This is typically used for EFI System Partitions.

mkfs.ext4 /dev/sdY2

Formats the second partition with the Ext4 filesystem

mkfs.ext4 /dev/sdY3

Formats the 3 partition with the Ext4 filesystem

6 - Mount the filesystem

Next, we mount the root filesystem, the home partition, and the EFI partition.

mount /dev/sdY2 /mnt

Mounts the second partition to /mnt

mkdir -vp /mnt/boot

Creates the /boot directory inside /mnt to mount the corresponding partition.

mount /dev/sdY2 /mnt/boot

Mounts the EFI system partition at /mnt/boot.

mkdir -vp /mnt/home

Creates the /home directory inside /mnt to mount the corresponding partition.

mount /dev/sdY3 /mnt/home

Mounts the Home partition at /mnt/home.

lsblk -pf /dev/sdY

Lists the partitions, filesystems, and mount points to verify everything is set up correctly.

7 - Install Base System

pacstrap -K /mnt linux linux-firmware linux-headers base base-devel nano \
		 networkmanager grub efibootmgr os-prober bash-completion iwd

Tip: You will need to add your CPU microcode package: for Intel, add intel-ucode; for AMD, add amd-ucode.


  • linux – The Linux kernel.
  • linux-firmware – Firmware files for various hardware devices.
  • linux-headers – Kernel headers for building modules against the kernel.
  • base – Essential packages for a minimal Arch Linux system.
  • base-devel – Development tools for compiling software (make, gcc, etc.).
  • nano – Simple terminal text editor.
  • networkmanager – Network management daemon and CLI tools.
  • grub – Bootloader to start the OS.
  • efibootmgr – EFI boot manager to configure UEFI boot entries.
  • os-prober – Detects other OS installations for bootloader configuration.
  • bash-completion – Bash completions for core commands.
  • iwd – Wireless daemon for managing Wi-Fi connections.
  • intel-ucode – Microcode updates for Intel CPUs.
  • amd-ucode – Microcode updates for AMD CPUs.

8 - Generate fstab

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

Generates the fstab file using UUIDs (-U) for all mounted partitions under /mnt, and writes it to /mnt/etc/fstab. This file tells the system which partitions to mount at boot.

9 - System Configuration

arch-chroot /mnt

Enters the new system environment at /mnt, so all following commands affect the installed system, not the live USB.

echo "zombie" > /etc/hostname

Sets the system name to zombie, Change it to your own hostname, which identifies your computer on networks.

timedatectl list-timezones | grep Tokyo

Use the above command with your city name to find your timezone. You can then use its output in the next command.

ln -sf /usr/share/zoneinfo/Japan/Tokyo /etc/localtime

Links your local timezone file to /etc/localtime for correct system time. Set it to your own localtime

hwclock --systohc

Writes the system time to the hardware clock so it stays accurate after reboots.

nano /etc/locale.gen

Uncomment the locale you want to use by removing the # and then save the file.

locale-gen

Generates the locale files specified in /etc/locale.gen.

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

Change the en_US.UTF-8 to the locale you uncommented in the /etc/locale.gen file.

echo "KEYMAP=us" > /etc/vconsole.conf

Add your own keymap by changing us to your keyboard layout.

passwd

Prompts to set a strong password for the root account.

useradd -mG wheel <yourUserName>

Creates the user with a home directory and adds them to the wheel group for administrative privileges. Replace <yourUserName> with your own username.

passwd <yourUserName>

Sets the password for your new user account.

EDITOR=nano visudo

Edits the sudoers file safely. This allows users in the wheel group to use sudo for administrative tasks. Uncomment the line at the bottom of the file by removing the # from: %wheel ALL=(ALL) ALL

10 - GRUB Dual Boot (Optional)

nano /etc/default/grub

Open the GRUB configuration file for editing. This file controls bootloader settings and kernel parameters.

GRUB_DISABLE_OS_PROBER=false     # Uncomment the line by removing the hashtag (#), then save and exit the file

This enables GRUB to detect and recognize other operating systems.

Use this only if you have another OS and want to dual boot between Arch Linux and that OS. You can skip this step if you don’t want to set up dual booting.

11 - Install GRUB

UEFI

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB --recheck

Installs GRUB for UEFI systems. - --efi-directory=/boot specifies the EFI system partition. - --bootloader-id=GRUB names the boot entry. - --removable makes it bootable on removable media. - --recheck ensures device detection is refreshed.

Generate GRUB configuration

grub-mkconfig -o /boot/grub/grub.cfg

Automatically generates the GRUB configuration file, detecting all kernels and operating systems.

12 - Networking, Hosts

systemctl enable systemd-networkd

Enables the systemd network service at boot, which manages network interfaces automatically.

systemctl enable systemd-resolved

Provides DNS resolution and caching for the system, required for hostname lookups and internet connectivity.

systemctl enable NetworkManager

A higher-level tool to manage wired, wireless, and VPN connections with CLI or GUI tools.

host=$(cat /etc/hostname)
sh -c "printf '127.0.0.1   localhost\n::1   localhost\n127.0.1.1   $host.localdomain   $host\n' > /etc/hosts"

Maps hostnames to IP addresses locally. This ensures your system can resolve its own hostname and loopback addresses without querying DNS.

13 - Desktop Environment (optional)

pacman -S xfce4 xfce4-goodies lightdm lightdm-gtk-greeter network-manager-applet \
	  bluez bluez-utils wget curl git xdg-utils gvfs openssh alsa-utils \

  • reflector – Updates/optimizes Arch Linux mirrors for faster package downloads.
  • cups – A Printing system

These packages install XFCE, essential utilities, audio/video support, network management, Bluetooth, and common CLI tools for daily usage.

systemctl enable lightdm

Starts the display manager automatically at boot, providing a login screen.

systemctl enable bluetooth

Starts the Bluetooth service automatically at boot for device pairing and management.

systemctl enable cups

Starts the printing service automatically at boot

14 - Finish

exit

Leaves the chroot environment, returning to the live installer system.

umount -R /mnt

Recursively unmounts all partitions mounted under /mnt, ensuring no filesystems are left mounted before shutdown.

poweroff

Shuts down the installer system safely. After this, you can remove the installation media and boot your new system.

Warning: Remove the installer USB and boot your computer.

15 - Post Installation

After booting and logging in as your user, the DNS step is important, while the YAY step is optional.

Let's set up the DNS

sh -c 'printf "nameserver 8.8.8.8\nnameserver 1.1.1.1\n" >> /etc/resolv.conf'

Adds public DNS servers (Google and Cloudflare) for name resolution. To ensures the system can resolve domain names on the internet.

Let's set up YAY, the AUR helper.

cd /tmp/ && git clone https://aur.archlinux.org/yay
cd yay/ && makepkgs -si --noconfirm

And now you can just use yay instead of pacman.

yay -Syu
yay -S fastfetch
fastfetch

Et voilà! You now have installed Arch Linux.
