This document is a guide for installing Arch Linux from the live system booted with the official installation image. Before installing, it would be advised to view the FAQ. If looking for a more detailed installation guide see the Beginners' guide, or Category:Getting and installing Arch for specific installation cases.
Most help can be found on the wiki or through the various programs' man pages; see archlinux(7) for an overview of the configuration. For interactive help, the IRC channel and the forums are also available.

- 3 Post-installation
Download and boot the installation medium as explained in Category:Getting and installing Arch, then proceed with the rest of this guide.
The installation process needs to retrieve packages from a remote repository, therefore a working internet connection is required.
Set the keyboard layout
The default keyboard layout is US. Alternative keyboard layouts can be loaded with
loadkeys keymap_file: keymap files can be found in
/usr/share/kbd/keymaps/ (path and file extension can be omitted).
Connect to the Internet
Internet service via DHCP discovery is enabled on boot for supported wired devices; read more at Network configuration. For supported wireless devices run
wifi-menu to set up the network; read more with Wireless network configuration. If needing a static IP or network management tools, stop
email@example.com and read Netctl.
Update the system clock
Partition the disks
See Partitioning for details; some special partitions may be needed, see EFI System Partition and GRUB BIOS boot partition. If wanting to create any stacked block devices for LVM, disk encryption or RAID, do it now.
Format the partitions
Mount the partitions
Mount the root partition on
/mnt. After that, create directories for and mount any other partitions (
/mnt/home, ...) and activate your swap partition if you want them to be detected later by genfstab.
Select the mirrors
/etc/pacman.d/mirrorlist and select a download mirror(s). Regional mirrors usually work best; however, other criteria may be necessary to discern, read more on Mirrors. This copy of the
mirrorlist file will later be copied on the new system by pacstrap, so it is worth getting it right.
Install the base packages
Use the pacstrap script to install the group:
# pacstrap /mnt base
Other packages or groups can be installed by appending their names to the above command (space separated), possibly including the boot loader.
Configure the system
Generate an fstab file (use
-L to define by UUID or labels):
# genfstab -p /mnt >> /mnt/etc/fstab
Change root into the new system:
# arch-chroot /mnt
Set the time zone:
# ln -s /usr/share/zoneinfo/zone/subzone /etc/localtime
Uncomment the needed locales in
/etc/locale.gen, then generate them with:
Add at least
/etc/locale.conf and possibly
Configure /etc/mkinitcpio.conf if additional features are needed. Create a new initial RAM disk with:
# mkinitcpio -p linux
Set the root password:
Install a boot loader
See Boot loaders for the available choices and configuration.
Exit the chroot environment by typing
exit or pressing
Optionally manually unmount all the partitions with
umount -R /mnt: this allows noticing any "busy" partitions, and finding the cause with fuser.
Finally, restart the machine by typing
reboot: any partitions still mounted will be automatically unmounted by systemd. Remember to remove the installation media and then login into the new system with the root account.
