Arch Linux is a free, open-source, rolling-release Linux distribution for x86_64 computers. A new installation ISO of about 1.5 GB is published regularly on archlinux.org, with SHA256 and BLAKE2b checksums and a PGP signature.
Arch Linux gives you a minimal base and leaves every other choice to you: desktop, apps, services. It is a rolling release, so once installed it is updated continuously. That freedom comes with responsibility, and Arch is best suited to users comfortable with the command line.
Getting the ISO
The download page lists the current release, a dated image (for example 2026.10.01) of about 1.5 GB, with HTTP mirrors and a BitTorrent link. The image is for x86_64 machines. It can be written straight to a USB flash drive, burned to a DVD or mounted in a virtual machine; with a wired connection you can also boot it over the network via Netboot.
Verify before you boot
The page lists SHA256 and BLAKE2b checksums and links the sha256sums.txt and b2sums.txt files, plus a PGP signature (.sig) for the ISO. With GnuPG, fetch the release signing key through WKD and then run gpg --verify on the .sig and ISO files, as shown on the download page. Do this especially if you downloaded from a mirror.
Installing
Arch has no graphical installer by default. You boot into a console and follow the Installation Guide on the Arch Wiki, which walks through partitioning, installing the base system and configuring the bootloader. The ISO also includes the guided archinstall script for a quicker setup.
Writing the USB
Rufus can write the ISO on Windows, and Ventoy can boot it from a multi-ISO stick. Partitioning is manual here, so back up your data and double-check the target disk before you format anything. If you want Arch’s packages with a friendlier start, look at Manjaro.
Pros
- Minimal base you shape yourself
- Rolling release with current software
- Signed ISO with two checksum types
Cons
- Installation is manual and console-based
- Not aimed at beginners
Frequently Asked Questions
Does Arch Linux have a graphical installer?
No. The official ISO boots to a console; you follow the Installation Guide on the Arch Wiki or use the included archinstall script.
How do I check that the Arch ISO is genuine?
Compare its checksum with sha256sums.txt or b2sums.txt and verify the PGP signature file with GnuPG or Sequoia, as described on the download page.
