Verdict: EndeavourOS 21.4 “Atlantis” delivered an Arch-based system that behaved much like Arch Linux while making installation substantially more approachable. Its live environment, graphical Calamares installer, Welcome application and community guidance were the key additions. Atlantis is historical installation media from December 2021, not a sensible image for a new installation today; use the current EndeavourOS download page after checking it at publication time.
What Atlantis was—and what it was not
Atlantis 21.4 was an EndeavourOS ISO release from December 2021. An archived mirror lists EndeavourOS_Atlantis-21_4.iso at 2,021,601,280 bytes (about 2.02 GB) and dates the file to 7 December 2021. That is the image’s file size, not a stated minimum disk or USB capacity.
EndeavourOS positions its installed system as running like Arch Linux. That makes “Arch-like” the accurate description: the distribution adds its own ISO, installation workflow, Welcome application and project tools rather than reproducing upstream Arch’s installation process unchanged. Atlantis should therefore be understood as an easier entry route into an Arch-style rolling system, not as the official Arch installer with a different name.
Recommended Free Tools
The Atlantis announcement described a refreshed ISO and said the release image was frozen at a particular point to avoid confusion around the release naming. It also mentioned community wallpapers and a default nvme_load=YES addition to GRUB’s kernel command line. That parameter was a targeted release change for recognition problems with certain PCIe-based M.2 drives; it is not a guarantee that every NVMe device will be detected.

How the installation experience differs from vanilla Arch
| Area | EndeavourOS Atlantis approach | Vanilla Arch approach |
|---|---|---|
| Initial setup | Boot a live ISO and use the project’s graphical installation layer. | Follow Arch’s manual installation workflow and documentation. |
| Guidance | Welcome utilities and EndeavourOS community resources supplement the system. | Arch documentation is the primary reference; there is no EndeavourOS layer. |
| Configuration responsibility | Less work is required to reach a usable desktop, but post-install administration remains yours. | You make and document more choices during installation and configuration. |
| Result | An Arch-based installation intended to behave much like Arch, with EndeavourOS choices and tools. | Arch Linux installed and configured directly from upstream packages and guidance. |
| Maintenance | Arch-style rolling updates, troubleshooting and system maintenance still apply. | The same rolling-release responsibilities apply. |
This is why EndeavourOS can suit someone who wants Arch’s package ecosystem and conventions but does not want to begin with a fully manual install. It does not remove the need to read update notices, understand package changes, maintain boot and graphics configuration, or recover from a problem.
Installer paths: online and offline
Current EndeavourOS documentation describes two installation modes built around a live ISO, KDE Plasma desktop, Welcome application and Calamares installer. Those documents explain the project’s installer model; they should not be treated as proof that every Atlantis-era screen or option was identical.

Offline installation
The offline route installs from packages available on the live image. It is useful when the target computer has no working internet connection during setup, but the resulting package set is limited to what the image contains. You should expect to update the system after first boot.
Online installation
The online route requires a working internet connection. It downloads a fresh base and selected desktop packages during installation, so the package set can be newer than the one embedded in the ISO and the desktop choice can be broader. A failed or unstable connection can interrupt the process.

| Choose | Best when | Trade-off |
|---|---|---|
| Offline | You need to install without internet access. | Uses the live image’s package set and normally needs updates afterward. |
| Online | You have reliable internet and want freshly downloaded packages or more desktop choices. | Installation depends on network access and download availability. |
Is EndeavourOS good for beginners?
It is beginner-friendly at the installation boundary, not a beginner-proof Linux system. Calamares and the live desktop reduce partitioning and setup friction, while the Welcome application and community provide orientation. Once installed, however, EndeavourOS follows Arch’s rolling model. Users still need to read notices before large updates, understand the package manager, keep backups and be prepared to diagnose boot, driver or desktop issues.
- A good fit: you want to learn an Arch-style system with a graphical starting point and community help.
- A questionable fit: you need long-term, fixed-version stability with minimal maintenance.
- Prepare first: back up important data, understand the difference between the online and offline paths, and have another device available for documentation if networking fails.
Is EndeavourOS “just Arch”?
No. The installed environment aims to run like Arch, but EndeavourOS contributes the live ISO, Welcome application, Calamares-based setup and project-specific defaults and support channels. Those additions change how you get to the system and where you look for help, even though Arch-style packages, rolling updates and administration remain central.

What the Atlantis release changed
The release announcement highlighted two user-visible details:
- NVMe boot parameter: the default GRUB kernel command line gained
nvme_load=YESto help certain PCIe-based M.2 drives be recognized. This was a narrow compatibility measure, not universal hardware support. - Community wallpapers: additional artwork from the community was included in the refreshed image.
The EndeavourOS release team wrote, “I hope we have given you the inspiration to give our Atlantis release a try because it was a pure pleasure for us to create it for you,” in the Atlantis announcement. No named performance, adoption or satisfaction statistics were established for this release, and there is no sound basis for inventing benchmarks from the ISO’s existence.
Should you install Atlantis today?
No, not for a normal fresh installation. Atlantis is archival media from 2021, and its package snapshot is necessarily old compared with later EndeavourOS releases. Use the project’s current download page instead, verify the image and read the current installation guidance. Atlantis remains useful when you are reviewing that historical release, reproducing a period-specific setup or studying how EndeavourOS presented its Arch-based approach at the time.
Bottom line for an Arch-curious reader
Atlantis made the first steps toward an Arch-like system easier without pretending to eliminate Arch’s learning curve. Choose EndeavourOS when you value a live desktop, graphical installer and community layer but are willing to maintain a rolling Linux installation. Choose vanilla Arch when the manual installation and configuration process is itself the goal. For either choice, install current media rather than the December 2021 Atlantis ISO.
