Getting and installing Arch
This category contains articles about Arch Linux releases, and downloading and installing Arch Linux.
It is recommended to verify the image signature before use, especially when downloading from an HTTP mirror, where downloads are generally prone to be intercepted to serve malicious images.
On a system with GnuPG installed, do this by downloading the PGP signature (under Checksums) to the ISO directory, and verifying it with
gpg --keyserver-options auto-key-retrieve --verify archlinux-<version>-x86_64.iso.sig.
pacman-key -v archlinux-<version>-x86_64.iso.sig from an existing Arch Linux installation.
- The signature itself could be manipulated if it is downloaded from a mirror site, instead of from archlinux.org as above. In this case, ensure that the public key, which is used to decode the signature, is signed by another, trustworthy key. The
gpgcommand will output the fingerprint of the public key.
- Another method to verify the authenticity of the signature is to ensure that the public key's fingerprint is identical to the key fingerprint of the Arch Linux developer who signed the ISO-file. See Wikipedia:Public-key_cryptography for more information on the public-key process to authenticate keys.
The table below offers an overview of the common ways to boot the installation media. As the installation process retrieves packages from a remote repository, these methods require an internet connection; see Offline installation of packages and Archiso#Installation without Internet access when none is available.
- Pointing the current boot device to a drive containing the Arch installation media is typically achieved by pressing a key during the POST phase, as indicated on the splash screen. Refer to your motherboard's manual for details.
- When the Arch menu appears, select Boot Arch Linux and press
Enterto enter the installation environment.
- If you opt for a multi boot installation using MBR partition table but your PC is UEFI-enabled, remember to boot the USB live in legacy mode to prevent issues with the bootloader.
- See README.bootparams for a list of boot parameters, and packages.both for a list of included packages.
