[Tutorial] Convert to systemd-boot

I’d like to apologize if reviving this topic from “5 months ago” will break any of this forum’s rules.

I’ve distro-hopped but always find my old self back in the Purple now this time with Cassini Nova. I had been an ArchBang fan up until yesterday - always with grub - and often getting rubbed out by grub over the years. My Linux knowledge is bits and pieces - never enough time for a cool Linux life.

So this tutorial I did read through and felt I understood the steps but … attempting it admittedly, with a solid ArchBang system running well and to my liking, the 2nd step stopped me instantly:

Next, we can cleanup /boot to prepare for the changes

sudo rm -r /boot/efi … right there. I believe I got “resource busy” . Yep, I was not in Endeavour but in ArchBang, and yep, I should know what I did wrong and why but nope, I don’t, and it’s probably something so obvious that even a bits & pieces old newbie should’ve realized … but I don’t.

I of course, did the first step, blowing grub away, which felt enjoyable, and of course, I couldn’t reboot. So with my trusty EOS Cassini USB stick, I’m back with you guys again.

Wasn’t I supposed to be within a WM/DE (I’m always in i3 with some xfce mixed in sometimes) and well past a successful grub boot? Nothing was wrong at all with grub nor with efibootmgr (dual boot on an iMac). I had no problems whatsoever. Just wanted to see if the tutorial would work. Nothing lost with my data, all backed up previously.

So can anyone clue me in on what marbles I’m missing?

Thank you - sorry for typing so much …
