Before you attempt these alternative Arch installation methods, I highly recommend installing Arch the traditional way: from the command line, step-by-step, using the classic Arch ISO. Why? Because ...

archinstall 4.0 replaces the curses interface with Textual, adds firewall and UKI support, and fundamentally modernizes the internal architecture.

No GUI, no problem.

A power user's delight, with just enough simplifications.
