Just another guided/automated Arch Linux installer with a twist. The installer also doubles as a python library to install Arch Linux and manage services, packages and other things inside the installed system (Usually from a live medium).

$ sudo pacman -S archinstall
Alternative ways to install are git clone the repository or pip install --upgrade archinstall.
Running the guided installer
Assuming you are on an Arch Linux live-ISO or installed via pip:
# archinstall
Running the guided installer using git
# cd archinstall-git
# cp archinstall/scripts/guided.py
# python guided.py
Some additional options that are not needed by most users are hidden behind the --advanced flag.
archinstall can be run with a JSON configuration file. There are 2 different configuration files to consider,
the user_configuration.json contains all general installation configuration, whereas the user_credentials.json
contains the sensitive user configuration such as user password, root password and encryption password.
An example of the user configuration file can be found here configuration file and example of the credentials configuration here credentials file.
HINT: The configuration files can be auto-generated by starting archinstall, configuring all desired menu
points and then going to Save configuration.
To load the configuration file into archinstall run the following command
archinstall --config <path to user config file or URL> --creds <path to user credentials config file or URL>
If any issues are encountered please submit an issue here on Github or submit a post in the discord help channel. When submitting an issue, please:
- Provide the stacktrace of the output if there is any
- Attach the
/var/log/archinstall/install.logto the issue ticket. This helps us help you!- To extract the log from the ISO image, one way is to use
curl -F'file=@/var/log/archinstall/install.log' https://0x0.st

Archinstall is available in different languages which have been contributed and are maintained by the community. The language can be switched inside the installer (first menu entry). Bare in mind that not all languages provide full translations as we rely on contributors to do the translations. Each language has an indicator that shows how much has been translated.
Any contributions to the translations are more than welcome, to get started please follow the guide
The ISO does not ship with ship with all fonts needed for different languages. Fonts that are using a different character set than Latin will not be displayed correctly. If those languages want to be selected than a proper font has to be set manually in the console.
All available console fonts can be found in /usr/share/kbd/consolefonts and can be set with setfont LatGrkCyr-8x16.
There are some examples in the examples/ directory that should serve as a starting point.
The following is a small example of how to script your own interactive installation:
from pathlib import Path
from archinstall import Installer, ProfileConfiguration, profile_handler, User
from archinstall.default_profiles.minimal import MinimalProfile
from archinstall.lib.disk.device_model import FilesystemType
from archinstall.lib.disk.encryption_menu import DiskEncryptionMenu
from archinstall.lib.disk.filesystem import FilesystemHandler
from archinstall.lib.interactions.disk_conf import select_disk_config
fs_type = FilesystemType('ext4')
# Select a device to use for the installation
disk_config = select_disk_config()
# Optional: ask for disk encryption configuration
data_store = {}
disk_encryption = DiskEncryptionMenu(disk_config.device_modifications, data_store).run()
# initiate file handler with the disk config and the optional disk encryption config
fs_handler = FilesystemHandler(disk_config, disk_encryption)
# perform all file operations
# WARNING: this will potentially format the filesystem and delete all data
fs_handler.perform_filesystem_operations()
mountpoint = Path('/tmp')
with Installer(
mountpoint,
disk_config,
disk_encryption=disk_encryption,
kernels=['linux']
) as installation:
installation.mount_ordered_layout()
installation.minimal_installation(hostname='minimal-arch')
installation.add_additional_packages(['nano', 'wget', 'git'])
# Optionally, install a profile of choice.
# In this case, we install a minimal profile that is empty
profile_config = ProfileConfiguration(MinimalProfile())
profile_handler.install_profile_config(installation, profile_config)
user = User('archinstall', 'password', True)
installation.create_users(user)This installer will perform the following:
- Prompt the user to configurate the disk partitioning
- Prompt the user to setup disk encryption
- Create a file handler instance for the configured disk and the optional disk encryption
- Perform the disk operations (WARNING: this will potentially format the disks and erase all data)
- Installs a basic instance of Arch Linux (base base-devel linux linux-firmware btrfs-progs efibootmgr)
- Installs and configures a bootloader to partition 0 on uefi. On BIOS, it sets the root to partition 0.
- Install additional packages (nano, wget, git)
- Create a new user
Creating your own ISO with this script on it: Follow ArchISO's guide on how to create your own ISO.
For an example of a fully scripted, automated installation please see the example full_automated_installation.py
Archinstall comes with an unattended
example which will look for a matching profile for the machine it is being run on, based on any local MAC address.
For instance, if the machine the code is executed on has the MAC address 52:54:00:12:34:56 it will look for a profile called
52-54-00-12-34-56.py.
If it's found, the unattended installation will commence and source that profile as its installation procedure.
archinstall ships with a set of pre-defined profiles that can be chosen during the installation process.
The definitions of the profiles and what packages they will install can be seen directly in the menu or default profiles
If you want to test a commit, branch or bleeding edge release from the repository using the vanilla Arch Live ISO image, you can replace the version of archinstall with a new version and run that with the steps described below.
*Note: When booting from a live USB then the space on the ramdisk is limited and may not be sufficient to allow running a re-installation or upgrade of the installer. In case one runs into this issue, any of the following can be used
- Resize the root partition on the fly https://wiki.archlinux.org/title/Archiso#Adjusting_the_size_of_root_partition_on_the_fly
- The boot parameter
copytoram=y(https://gitlab.archlinux.org/archlinux/mkinitcpio/mkinitcpio-archiso/-/blob/master/docs/README.bootparams#L26) can be specified which will copy the root filesystem to tmpfs.*
- You need a working network connection
- Install the build requirements with
pacman -Sy; pacman -S git python-pip gcc pkgconf(note that this may or may not work depending on your RAM and current state of the squashfs maximum filesystem free space) - Uninstall the previous version of archinstall with
pip uninstall --break-system-packages archinstall - Now clone the latest repository with
git clone https://github.com/archlinux/archinstall - Enter the repository with
cd archinstallAt this stage, you can choose to check out a feature branch for instance withgit checkout v2.3.1-rc1 - To run the source code, there are 2 different options:
- Run a specific branch version from source directly using
python -m archinstall, in most cases this will work just fine, the rare case it will not work is if the source has introduced any new dependencies that are not installed yet - Installing the branch version with
pip install --break-system-packages .andarchinstall
- Run a specific branch version from source directly using
To test this without a live ISO, the simplest approach is to use a local image and create a loop device.
This can be done by installing pacman -S arch-install-scripts util-linux locally and doing the following:
# truncate -s 20G testimage.img
# losetup --partscan --show --find ./testimage.img
# pip install --upgrade archinstall
# python -m archinstall --script guided
# qemu-system-x86_64 -enable-kvm -machine q35,accel=kvm -device intel-iommu -cpu host -m 4096 -boot order=d -drive file=./testimage.img,format=raw -drive if=pflash,format=raw,readonly,file=/usr/share/ovmf/x64/OVMF_CODE.fd -drive if=pflash,format=raw,readonly,file=/usr/share/ovmf/x64/OVMF_VARS.fd
This will create a 20 GB testimage.img and create a loop device which we can use to format and install to.
archinstall is installed and executed in guided mode. Once the installation is complete, you can use qemu/kvm to boot the test media.
(You'd actually need to do some EFI magic in order to point the EFI vars to the partition 0 in the test medium, so this won't work entirely out of the box, but that gives you a general idea of what we're going for here)
There's also a Building and Testing guide.
It will go through everything from packaging, building and running (with qemu) the installer against a dev branch.
archinstall can be used to install Arch alongside an existing Windows installation.
Below are the necessary steps:
- After the Windows installation make sure there is some unallocated space for a Linux installation available
- Boot into the ISO and run
archinstall - Select
Disk configuration->Manual partitioning - Select the disk on which Windows resides
- Chose
Create a new partition - Select a filesystem type
- Now the location of the new partition has to be specified as start and end sectors (values can be suffixed with various units)
- Assign mountpoint
/ - Back in the partitioning menu, assign the
Boot/ESPpartition the mountpoint/boot - This is all for the partitioning menu, select
Confirm and exitto return to the main menu - Set any additional settings you would like to have for the installation
- After completing the setup start the installation
Archinstall promises to ship a guided installer that follows the Arch Principles as well as a library to manage services, packages and other Arch Linux aspects.
The guided installer will provide user-friendly options along the way, but the keyword here is options, they are optional and will never be forced upon anyone. The guided installer itself is also optional to use if so desired and not forced upon anyone.
Archinstall has one fundamental function which is to be a flexible library to manage services, packages and other aspects inside the installed system. This library is in turn used by the provided guided installer but is also for anyone who wants to script their own installations.
Therefore, Archinstall will try its best to not introduce any breaking changes except for major releases which may break backwards compatibility after notifying about such changes.
