Download the installation medium
It is recommended to verify the image signature before use, especially when downloading from an HTTP mirror, because mirrors could be malicious and HTTP is vulnerable to man-in-the-middle attacks (unless you use HTTPS).
gpg --keyserver pgp.mit.edu --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 as root.
- 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.
- Write the image on flash media or optical disc, then boot from it.
- Mount the image on a server machine and have clients boot it over the network. See PXE and Diskless system.
- Install Arch Linux via SSH. See Install from SSH.
- Mount the image in a running Linux system and install Arch from a chroot environment. See Install from existing Linux.
- Install Arch Linux in a virtual machine. See also Moving an existing install into (or out of) a virtual machine.
- Install Arch next to a Windows installation. See Dual boot with Windows.
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.
- See README.bootparams for a list of boot parameters, and packages.x86_64 for a list of included packages.
