Finishing Up

  1. Exit the arch-chroot environment: exit
  2. Unmount BOOT: umount /mnt/boot
  3. Unmount ROOT: umount /mnt
  4. Reboot and remove the USB: reboot

Final words

That's it! You now have a basic working installation of arch. It's worth noting that you, following these steps, won't have a graphical interface but this can be added. I won't go through that in this guide but there are plenty of resources elsewhere.
