How to Install Arch Linux (2025 Updated Beginner Guide)

Arch Linux is one of the most customizable, lightweight, and fast Linux distributions available today. However, it doesn't have a graphical installer like Ubuntu "" you install everything manually.

This guide will help beginners install Arch Linux from scratch "" on PCs, laptops, or even virtual machines "" with detailed commands, partition setup, desktop environment installation, and boot troubleshooting.

👑§© Prerequisites

Before starting, make sure you have:

• A USB drive (at least 4 GB)
• A stable internet connection
• A computer (PC or laptop) that supports UEFI (most modern systems do)
• Optional: Another device or phone to follow this guide while installing

âš™ï¸ Step 1: Download Arch Linux ISO

Visit the official Arch Linux download page: 👑"— https://archlinux.org/download/

Download the latest ISO file (e.g. archlinux-2025.10.01-x86_64.iso)

Verify the download (optional but recommended):

sha256sum archlinux-2025.10.01-x86_64.iso

Compare it with the checksum on the website.

👑’½ Step 2: Create a Bootable USB

👑ªŸ On Windows: Use Rufus:

1. Download Rufus
2. Select your Arch ISO file.
3. Choose your USB drive.
4. Under Partition Scheme, select:
   • GPT if your system uses UEFI
   • MBR if it uses Legacy BIOS
5. Click Start and wait.

👑§ On Linux: Use the dd command:

sudo dd if=archlinux-2025.10.01-x86_64.iso of=/dev/sdX bs=4M status=progress oflag=sync

(Replace /dev/sdX with your USB drive path "" e.g. /dev/sdb)

👑–¥ï¸ Step 3: Boot Into the Arch Installer

1. Plug the USB into your system.
2. Reboot and open the Boot Menu (usually by pressing F2, F12, or Esc during startup).
3. Select your USB drive.
4. When the Arch menu appears, choose: "Arch Linux install medium (x86_64, UEFI)"

You'll land in a terminal (root@archiso).

👑Œ Step 4: Connect to the Internet

For wired (Ethernet): You're already connected.

For Wi-Fi: Run:

iwctl

Then inside the prompt:

device list
station wlan0 scan
station wlan0 get-networks
station wlan0 connect "Your_WiFi_Name"
exit

Test the connection:

ping archlinux.org

If you see replies "" you're online ✅

🕐" Step 5: Update System Clock

timedatectl set-ntp true

👑’¾ Step 6: Partition Your Disk

List your drives:

fdisk -l

Identify your target drive (e.g. /dev/sda or /dev/nvme0n1).

Using cfdisk (simpler):

cfdisk /dev/sda

Select GPT.

Now create:

1. EFI Partition →’ 512MB →’ Type: EFI System
2. Root Partition →’ remaining space →’ Type: Linux filesystem
3. If you want a swap partition, create it too (e.g., 2GB).

Then: Write →’ Yes →’ Quit.

👑§± Step 7: Format the Partitions

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

👑"‚ Step 8: Mount the Filesystems

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

👑"§ Step 9: Install the Base System

pacstrap /mnt base linux linux-firmware vim networkmanager

👑’¡ You can replace vim with nano if you prefer.

📜 Step 10: Generate fstab

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

👑"„ Step 11: Chroot into the New System

arch-chroot /mnt

â° Step 12: Set Timezone and Locale

ln -sf /usr/share/zoneinfo/Asia/Karachi /etc/localtime
hwclock --systohc

Edit locales:

nano /etc/locale.gen

Uncomment: en_US.UTF-8 UTF-8

Generate locales:

locale-gen

Create locale config:

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

👑‘¤ Step 13: Set Hostname and Root Password

echo "archpc" > /etc/hostname
echo "127.0.0.1   localhost" >> /etc/hosts
echo "::1         localhost" >> /etc/hosts
echo "127.0.1.1   archpc.localdomain archpc" >> /etc/hosts
passwd

👑§  Step 14: Enable Network Manager

systemctl enable NetworkManager

👑¥¾ Step 15: Install and Configure Bootloader (GRUB)

Install GRUB and EFI tools:

pacman -S grub efibootmgr

Install GRUB to disk:

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

👑§‘"👑’» Step 16: Create a User
