Features

• Full-disk encryption – LUKS2, unlocked once at boot
• Btrfs + Snapper – automatic snapshots before and after every update, plus a clean-state boot entry
• CachyOS kernel – performance-tuned kernel with automatic GPU driver detection (NVIDIA, AMD, Intel, hybrid laptops)
• GNOME desktop – Windows-style taskbar and start menu, window snapping (halves, quarters, full screen)
• Gaming ready – Steam, Lutris, Heroic, ProtonUp-Qt and GE-Proton out of the box
• Single or dual boot – wipe a drive, or install next to Windows in free space
• NTFS + USB – Windows drives usable straight away; USB sticks auto-mount and are repaired if dirty
• Wi-Fi hotspot – optional, kept up automatically from boot
• niix-update – one command for system, AUR, Flatpak and firmware updates, checking Arch news first
• No nags – donation pop-ups turned off

Requirements

• 64-bit (x86_64) PC with UEFI (no legacy BIOS)
• Secure Boot turned off (Limine, the bootloader, doesn't support it)
• An internet connection (Ethernet or Wi-Fi)
• The Arch Linux ISO on a USB stick
• Disk space:
  • Single boot: a drive you're willing to completely wipe
  • Dual boot: unallocated space next to Windows
  • 64 GB or more is recommended; games need more

How to run

1. Download the Arch Linux ISO

https://archlinux.org/download/

2. Put it on a USB stick

Use balenaEtcher (https://etcher.balena.io) to write the ISO to a USB stick, or install Ventoy (https://www.ventoy.net) on the stick and copy the ISO onto it.

3. Boot from the USB stick

1. In your BIOS, turn Secure Boot off.
2. Restart and open the boot menu (usually F12, F11 or Esc).
3. Pick the USB stick, then Arch Linux install medium.

4. Connect to Wi-Fi

Skip this step if you use a network cable.

Type:

iwctl

Then type this, using your Wi-Fi name (keep the quotes):

station wlan0 connect "YOUR-WIFI-NAME"

Enter your Wi-Fi password when asked, then press Ctrl + C to leave.

5. Run the installer

bash <(curl -fsSL https://niixa.org/install)

Answer the questions and the installer does the rest. After it reboots, unlock the disk with your passphrase; the first login finishes the setup automatically.

Optional – verify the installer before running it:

curl -fsSLo install https://niixa.org/install && curl -fsSL https://raw.githubusercontent.com/techniixdotcom/niixarch-install/main/install.sha256 | grep ' install$' | sha256sum -c && bash install
