The community-maintained ArchWiki is the primary resource that should be consulted if issues arise. The IRC channel (irc://irc.freenode.net/#archlinux) and the forums are also excellent resources if an answer cannot be found elsewhere. In accordance with the Arch Way, you are encouraged to type
man command to read the man page of any command you are unfamiliar with.
Alt+arrow) between the console containing the web page, and the console where you are performing the installation. Similarly, the
#archlinuxIRC can be accessed using irssi.
Arch Linux should run on any i686 compatible machine with a minimum of 256 MB RAM. A basic installation with all packages from the group should take less than 800 MB of disk space.
See Category:Getting and installing Arch for instructions on downloading the installation medium, and methods for booting it to the target machine(s). This guide assumes you use the latest available version.
After booting into the installation media, you will be automatically logged in as the root user and presented with a Zsh shell prompt. For modifying or creating configuration files, typically in
/etc, nano or vim are suggested.
To verify you are booted in UEFI mode, check that the following directory is populated:
# ls /sys/firmware/efi/efivars
See UEFI#UEFI Variables for details.
Set the keyboard layout
localectl list-keymapsdoes not work due to bug FS#46725.
For example, to change the layout to
# loadkeys de-latin1
If certain characters appear as white squares or other symbols, change the console font. For example:
# setfont lat9w-16
Connect to the Internet
Verify a connection was established, for example with
ping archlinux.org. If no connection is available, see Network configuration or follow the below netctl examples. Otherwise, continue to #Update the system clock.
- Netctl preparation
To prevent conflicts, stop the enabled dhcpcd service first, replacing
enp0s25 with the correct wired interface:
# systemctl stop firstname.lastname@example.org
Interfaces can be listed using
ip link, or
iw dev for wireless devices. They are prefixed with
wl (WLAN), or
List available networks, and make a connection for a specified interface:
# wifi-menu -o wlp2s0
The resulting configuration file is stored in
/etc/netctl. For networks which require both a username and password, see WPA2 Enterprise#netctl.
Several example profiles, such as for configuring a static IP address, are available. Copy the required one to
/etc/netctl, for example
# cp /etc/netctl/examples/ethernet-static /etc/netctl
Adjust the copy as needed, and enable it:
# netctl start ethernet-static
Update the system clock
Use systemd-timesyncd to ensure that your system clock is accurate. To start it:
# timedatectl set-ntp true
To check the service status, use
Prepare the storage devices
In this step, the storage devices that will be used by the new system will be prepared. Read Partitioning for a more general overview.
Users intending to create stacked block devices for LVM, disk encryption or RAID, should keep those instructions in mind when preparing the partitions. If intending to install to a USB flash key, see Installing Arch Linux on a USB key.
Identify the devices
Identify the devices where the new system will be installed:
Not all devices listed are viable mediums for installation; results ending in
airoot can be ignored.
sdxynotation will be used (
xfor the device,
yfor an existing partition).
If the existing partition scheme does not need to be changed, you may skip to #Format the partitions.
Partition the devices
Partitioning a hard drive divides the available space into sections that can be accessed independently. The required information is stored in a partition table using a format such as MBR or GPT. Existing tables can be printed with
parted /dev/sdx print or
fdisk -l /dev/sdx.
To partition devices, use a partitioning tool compatible to the chosen type of partition table. Incompatible tools may result in the destruction of that table, along with existing partitions or data. Choices include:
The examples below demonstrate a basic partition scheme for both types of partition tables. They assume that a new, contiguous layout is applied to a single device in
/dev/sdx. Necessary changes to device names and partition numbers must be done beforehand.
|UEFI/GPT example layout|
|Mount point||Partition||Partition type (GUID)||Bootable flag||Suggested size|
|/boot||/dev/sdx1||EFI System Partition||Yes||260–512 MiB|
|[SWAP]||/dev/sdx2||Linux swap||No||More than 512 MiB|
|/||/dev/sdx3||Linux||No||Remainder of the device|
|MBR/BIOS example layout|
|Mount point||Partition||Partition type||Bootable flag||Suggested size|
|[SWAP]||/dev/sdx1||Linux swap||No||More than 512 MiB|
|/||/dev/sdx2||Linux||Yes||Remainder of the device|
Format the partitions
Once the partitions have been created, each must be formatted with an appropriate file system, except for swap partitions. All available partitions on the intended installation device can be listed with the following command:
# lsblk /dev/sdx
With the exceptions noted below, it is recommended to use the
ext4 file system:
# mkfs.ext4 /dev/sdxy
If a swap partition was created, it must be set up and activated with:
# mkswap /dev/sdxy # swapon /dev/sdxy
If a new UEFI system partition has been created on a UEFI/GPT system, it must be formatted with a
fat32 file system:
# mkfs.fat -F32 /dev/sdxy
Mount the partitions
Mount the root partition to the
/mnt directory of the live system:
# mount /dev/sdxy /mnt
Remaining partitions except swap may be mounted in any order, after creating the respective mount points. For example, when using a
# mkdir -p /mnt/boot # mount /dev/sdxy /mnt/boot
/mnt/boot is also recommended for mounting the (formatted or already existing) EFI System Partition on a UEFI/GPT system. See EFISTUB and related articles for alternatives.
Select the mirrors
Packages to be installed must be downloaded from mirror servers, which are defined in
/etc/pacman.d/mirrorlist. On the live system, all mirrors are enabled, and sorted by their synchronization status and speed at the time the installation image was created.
The higher a mirror is placed in the list, the more priority it is given when downloading a package. You may want to edit the file accordingly, and move the geographically closest mirrors to the top of the list, although other criteria should be taken into account.
The pacstrap tool used in the next step also installs a copy of the file to the new system, so it is worth getting right.
Install the base packages
Use the kernel and firmware for common hardware:script to install the package, Linux
# pacstrap -i /mnt base linux linux-firmware
-i switch ensures prompting before package installation.
With the base group, the first initramfs will be generated and installed to the new system's boot path; double-check output prompts
==> Image creation successful for it.
To build packages from the AUR or with the ABS, the group is also required. Packages can be installed with anytime after the #Change root step later, or by appending their names to the pacstrap command.
# genfstab -U /mnt >> /mnt/etc/fstab
Check the resulting file in
/mnt/etc/fstab afterwards, and edit it in case of errors.
Chroot to the new system:
# arch-chroot /mnt /bin/bash
The Locale defines which language the system uses, and other regional considerations such as currency denomination, numerology, and character sets.
en_US.UTF-8 UTF-8 in
/etc/locale.gen, as well as other needed localisations. Save the file, and generate the new locales:
en_US.UTF-8 refers to the first column of an uncommented entry in
If you set the keyboard layout, make the changes persistent in
/etc/vconsole.conf. For example, if
de-latin1 was set with loadkeys, and
lat9w-16 with setfont, assign the
FONT variables accordingly:
Select a time zone:
Create the symbolic link
Zone/Subzone is the
TZ value from tzselect:
# ln -s /usr/share/zoneinfo/Zone/SubZone /etc/localtime
It is recommended to adjust the time skew, and set the time standard to UTC:
# hwclock --systohc --utc
If other operating systems are installed on the machine, they must be configured accordingly. See Time for details.
Because mkinitcpio was run on installation of with pacstrap, most users do not need to regenerate the intramfs image so this step can be skipped.
# mkinitcpio -p linux
If you have an Intel CPU, in addition to installing a boot loader, install the enable microcode updates.package and
The procedure is similar to #Connect to the Internet for the live installation environment, except made persistent for subsequent boots.
It is recommended to append the same host name to
/etc/hosts, for example:
127.0.0.1 localhost.localdomain localhost myhostname ::1 localhost.localdomain localhost myhostname
# systemctl enable email@example.com
interface is an ethernet device name.
See Network configuration#Configure the IP address for other available methods.
# pacman -S iw wpa_supplicant dialog
See Wireless#Wireless management for other available methods.
Set the root password with:
Unmount the partitions and reboot
Exit from the chroot environment by running
exit or pressing
Partitions will be unmounted automatically by systemd on shutdown. You may however unmount manually as a safety measure:
# umount -R /mnt
If the partition is "busy", you can find the cause with fuser. Reboot the computer.
Remove the installation media, or you may boot back into it. You can log into your new installation as root, using the password you specified with passwd.
Your new Arch Linux base system is now a functional GNU/Linux environment ready to be built into whatever you wish or require for your purposes. You are now strongly advised to read the General recommendations article, especially the first two sections. Its other sections provide links to post-installation tutorials like setting up a graphical user interface, sound or a touchpad.
