Pre-Installation Preparation

1. Boot the Arch Linux ISO: After booting from the Arch Linux installation media, you will be presented with a root shell prompt. This Arch Linux installation guide begins by verifying your internet connectivity:

   # ping -c 3 archlinux.org

   If the ping succeeds, you have internet access and can proceed with the Arch Linux installation guide.

2. Identify your target disk: List all available block devices to identify which disk you want to install Arch Linux on:

   # lsblk

   Note the device name of your target disk (e.g., /dev/sda, /dev/nvme0n1, or /dev/vda). This Arch Linux installation guide uses /dev/sda as an example.

Disk Partitioning for Arch Linux

1. Launch the partition tool: This Arch Linux installation guide uses cfdisk to create a GPT partition table:

   # cfdisk /dev/sda

   When prompted, select gpt as the label type for UEFI systems.

2. Create the EFI partition: Select “New” and create the first partition with a size of 512M. Then select “Type” and change it to EFI System.

   Size: 512M
   Type: EFI System

   This partition will store the bootloader and UEFI boot files required for the Arch Linux installation.

3. Create the root partition: Select the remaining free space, choose “New”, and press Enter to use all remaining space as the root partition.

   Size: (remaining space)
   Type: Linux filesystem

   This will be your main Arch Linux system partition.

4. Write changes to disk: Select “Write” at the bottom of the screen, type yes to confirm, then select “Quit” to exit cfdisk.

   Confirm: yes

   Your partition table has now been written to the disk.

   

Format and Mount Partitions

1. Format the EFI partition: Create a FAT32 filesystem on the EFI partition as required by this Arch Linux installation guide:

   # mkfs.fat -F32 /dev/sda1

   The EFI partition must use FAT32 format for UEFI compatibility in any Arch Linux installation.

2. Format the root partition: Create an ext4 filesystem on the root partition:

   # mkfs.ext4 /dev/sda2

   Ext4 is the standard Linux filesystem providing excellent performance and reliability for Arch Linux.

3. Mount the root partition: Mount the root partition to /mnt:

   # mount /dev/sda2 /mnt

   This makes the root filesystem accessible for the Arch Linux installation.

4. Mount the EFI partition: Create and mount the boot directory:

   # mount --mkdir /dev/sda1 /mnt/boot

   The --mkdir flag automatically creates the boot directory if it doesn’t exist during this Arch Linux installation guide.

   

Install Base Arch Linux System

1. Install essential packages: Use pacstrap to install the base Arch Linux system, Linux kernel, and firmware:

   # pacstrap -K /mnt base linux linux-firmware

   This command installs the minimal packages required for a functional Arch Linux system. The process typically takes several minutes depending on your internet connection. This is the core step of any Arch Linux installation guide.

2. Generate fstab: Create the filesystem table that defines how partitions are mounted at boot in your Arch Linux installation:

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

   The -U flag uses UUIDs to identify partitions, making the Arch Linux system more resilient to device name changes.

   

Arch Linux System Configuration

1. Enter the new system: Change root into the newly installed Arch Linux system:

   # arch-chroot /mnt

   You are now operating within your new Arch Linux installation.

2. Set timezone: Create a symbolic link to your timezone. This Arch Linux installation guide uses Warsaw as an example, but you can adjust for your location:

   # ln -sf /usr/share/zoneinfo/Europe/Bratislava /etc/localtime

   Then synchronize the hardware clock:

   # hwclock --systohc

   This ensures your Arch Linux system time is correctly configured.

3. Configure locale: Generate the locale configuration for your Arch Linux system:

   # echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen
   # locale-gen

   Then set the system locale:

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

   These commands enable UTF-8 encoding for proper character support in Arch Linux.

4. Set hostname: Choose a name for your Arch Linux computer. This Arch Linux installation guide uses linuxconfig as an example:

   # echo "linuxconfig" > /etc/hostname

   You can replace linuxconfig with any hostname you prefer, such as archbox, myarch, or workstation.

5. Set root password: Create a secure password for the root account on your Arch Linux system:

   # passwd

   Enter and confirm your password when prompted. Choose a strong password for security.

   

Bootloader Installation for Arch Linux

1. Install required packages: Install the bootloader and network management tools for Arch Linux:

   # pacman -S grub efibootmgr networkmanager

   Press Enter to accept default selections. NetworkManager will handle network connectivity after your Arch Linux installation is complete.

2. Install GRUB bootloader: For UEFI systems, install GRUB to the EFI partition:

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

   This installs GRUB as the bootloader for your Arch Linux system. You may see warnings about EFI variables in virtual machine or chroot environments, which can be safely ignored.

3. Generate GRUB configuration: Create the GRUB configuration file that defines boot options:

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

   GRUB will automatically detect your Linux kernel and create the appropriate boot entries for your Arch Linux installation.

   UEFI BOOT FIX FOR VIRTUAL MACHINES
   If you are installing Arch Linux in a virtual machine and the system fails to boot after a complete power off (but works after reboot), you need to create a fallback UEFI boot entry. After the GRUB installation step, run these additional commands: mkdir -p /boot/EFI/BOOT and cp /boot/EFI/GRUB/grubx64.efi /boot/EFI/BOOT/BOOTX64.EFI. This copies GRUB to the default UEFI fallback path that firmware always checks, ensuring the system boots even after a complete shutdown.

4. Enable NetworkManager: Ensure network connectivity after your Arch Linux installation is complete:

   # systemctl enable NetworkManager

   This configures NetworkManager to start automatically when you boot into Arch Linux.

   

Desktop Environment Installation on Arch Linux

1. Install GNOME: Install the complete GNOME desktop environment on your Arch Linux system:

   # pacman -S gnome

   You will be prompted with several selections during the GNOME installation:

   • GNOME group packages: When asked to select from 58 members in group gnome, press Enter to install all packages (default=all). This includes essential components like gdm, gnome-shell, nautilus, and various GNOME applications.
   • Font provider: When asked to choose from 11 ttf-font providers, press Enter to accept the default (gnu-free-fonts). All options provide adequate font support for your Arch Linux installation.
   • Audio system: When asked to choose between jack2 and pipewire-jack, press Enter to accept the default (jack2). Both options work well with GNOME on Arch Linux.

   The installation process takes several minutes to download and install all packages.

2. Enable display manager: Configure GDM (GNOME Display Manager) to start at boot on your Arch Linux system:

   # systemctl enable gdm

   GDM provides the graphical login screen for your Arch Linux installation.

User Account Creation on Arch Linux

1. Create a user account: Add a new user with home directory and wheel group membership. This Arch Linux installation guide uses linuxconfig as the username:

   # useradd -m -G wheel linuxconfig

   You can replace linuxconfig with your preferred username, such as john, admin, or any name you choose. The -m flag creates a home directory, and -G wheel adds the user to the wheel group for sudo privileges on your Arch Linux system.

2. Set user password: Assign a password to the new user in your Arch Linux installation:

   # passwd linuxconfig

   Replace linuxconfig with the username you created. Enter and confirm the password when prompted.

3. Install and configure sudo: Install sudo for privilege elevation on Arch Linux:

   # pacman -S sudo

   Then enable sudo access for wheel group members by editing the sudoers file:

   # EDITOR=nano visudo

   If nano is not available, you can install it first with pacman -S nano. Uncomment (remove the #) from the line:

   %wheel ALL=(ALL:ALL) ALL

   Save and exit. Users in the wheel group can now use sudo on your Arch Linux system.

   

Complete Arch Linux Installation

1. Exit chroot environment: Return to the live environment:

   # exit

   You are now back in the installation media environment, having completed the core steps of this Arch Linux installation guide.

2. Unmount partitions: Safely unmount all partitions:

   # umount -R /mnt

   This ensures all data is written to disk before rebooting your new Arch Linux system.

3. Reboot system: Restart into your new Arch Linux installation:

   # reboot

   Remove or disconnect the installation media when prompted. Your Arch Linux system should boot to the GNOME login screen.

Frequently Asked Questions

1. What if my Arch Linux system doesn’t boot after installation? First, verify your BIOS/UEFI is set to boot in UEFI mode, not legacy BIOS. Boot from the Arch Linux ISO again, mount your partitions with mount /dev/sda2 /mnt and mount /dev/sda1 /mnt/boot, then enter chroot with arch-chroot /mnt. Reinstall GRUB and regenerate the configuration with grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB followed by grub-mkconfig -o /boot/grub/grub.cfg. For virtual machines, ensure you’ve created the fallback boot entry as described in the troubleshooting section.
2. Can I install Arch Linux alongside Windows or another Linux distribution? Yes, dual-booting is possible but requires careful partitioning. Do not format the existing EFI partition if one exists from Windows. Instead, mount the existing EFI partition to /mnt/boot and install GRUB there. GRUB’s os-prober package can detect other operating systems. Install it with pacman -S os-prober, enable it in /etc/default/grub by adding GRUB_DISABLE_OS_PROBER=false, then regenerate the GRUB configuration.
3. How do I partition my disk for Arch Linux installation? For UEFI systems, create a GPT partition table using cfdisk /dev/sda. You need at minimum two partitions: a 512MB EFI System partition formatted as FAT32, and a root partition using the remaining space formatted as ext4. Optionally, create a separate home partition for user data or a swap partition for hibernation support. The EFI partition stores bootloader files while the root partition contains the entire Arch Linux system.
4. How do I install Arch Linux without UEFI (legacy BIOS)? This guide covers UEFI installation only. For legacy BIOS systems, use MBR partitioning instead of GPT by selecting dos label type in cfdisk. You won’t need an EFI partition. Install GRUB differently with grub-install --target=i386-pc /dev/sda (note: use the disk, not a partition). The rest of the installation process remains similar. Consult the official Arch Wiki installation guide for detailed BIOS-specific instructions.
