How to install CachyOS

Installing CachyOS

CachyOS is a powerful and feature-rich operating system, but it can be intimidating to install for the first time. This guide will walk you through the process, step-by-step, so you can have CachyOS up and running on your computer in no time.

System Requirements

Before you begin the installation, please ensure that your computer meets the following minimum system requirements:

  • 3 GB of memory
  • 30 GB of hard disk space
  • 1 GHz processor
  • HD graphics card and monitor
  • Broadband internet connection

For the best performance, it is recommended to have:

  • 4 GB of memory
  • 50 GB of hard disk space
  • An x86-64-v3 supported processor
  • 50 Mbps or better internet connection
  • A newer NVIDIA card (900+), AMD Graphics Card or Intel

Choosing Your Bootloader

CachyOS offers three different bootloaders for online installation: systemd-boot, Grub(3) and rEFInd. You will be asked to choose between the three when you click the Launch Installer button in CachyOS Hello. We recommend using systemd-boot as it is the simplest and results in faster boot times.

  • systemd-boot supports any filesystem.
  • Grub has some limitations with zfs and does not support all features of zfs but otherwise supports all filesystems.
  • rEFInd supports any filesystem.

Choosing Your Filesystem

When you install CachyOS, you can choose from the following five filesystems: xfs, ext4, btrfs, f2fs, and zfs.

  • XFS is a high-performance journaling file system that is particularly good at parallel I/O.
  • Ext4 is the evolution of the widely used Ext3 file system and offers improved performance, reliability, and features.
  • Btrfs is a modern copy-on-write filesystem with advanced features and a focus on fault tolerance and easy administration.
  • F2FS is a file system designed for NAND-based flash memory.
  • ZFS is an advanced file system created by Sun Microsystems that offers stability, speed, security, and future-proofing.

Offline Installation Keyring issue

Terminal window
sudo pacman-key --init; sudo pacman-key --populate; sudo pacman-key --lsign cachyos

KDE Plasma Wayland Taskbar not working

With Plasma 6 and a fresh Installation plasma seems to have issues when clicking on the taskbar, for example on the networkmanager icon. This can be simply resolved when logging into X11 instead of Plasma Session, clicking on the networkmanager button and then go back to Wayland

This is an upstream bug and should be solved in the future.
