Recently wanted to try KDE 6 on my second laptop and after being pissed off at the lack of encryption with Void installer (gotta do it manually, have done it in the past but I'm lazy), another fail with NixOs (known bug with encryption in the latest stable installer) the easiest way was installing Arch lol.
I used archinstall as suggested, just answer questions, no manual voodoo incantation required. You can do it.
The time you took to answer the archinstall questions and what would take to do them manually is (nearly) the same. The manual way is that you are forced learn the system (which does take time), and it's thus more exact of what you want. Once you successfully boot a manual install on a bare hardware, you'll get all the swag. ;)
(I was lazy last time I had to do a full install, and I prepared the system almost entirely in a VM, for which I used the physical disk I would finally boot it from. The final step was to chroot'd into the nearly complete system and make it boot outside of the VM...)
