One ISO. Minimal live environment: a shell, pacman, fish, yay. That's it.
Write to USB
Use dd on Linux/macOS. Verify the device path before running — this will erase the target device completely.
lsblk. Writing to the wrong device means data loss.Boot the live environment
Plug in the USB, reboot, enter your firmware's boot menu (F12, F2, Del, or Esc depending on your board), and select the USB drive. You'll land at a TTY as root.
Install manually
Since there's no installer yet, follow the standard Arch Linux installation procedure. The Arch installation guide applies directly — the live environment has everything needed: pacstrap, arch-chroot, genfstab, fdisk.
- Partition your disk with
fdiskorcfdisk - Format and mount partitions under
/mnt - Install the base system:
pacstrap -K /mnt base linux linux-firmware - Generate fstab:
genfstab -U /mnt >> /mnt/etc/fstab - Chroot in:
arch-chroot /mnt - Set timezone, locale, hostname, root password
- Install a bootloader (grub or systemd-boot)
- Exit chroot, unmount, reboot
After first boot into the installed system, install whatever you need — a DE, a display manager, drivers. The wiki has post-install suggestions.
