I wanted to know which one of these are safe to delete. I guess the empty Linux folder and the EndeavourOS folder with only grubx64.efi should be fine.
It should be rm -r instead of rm as we’re deleting directories. And simply deleting the EndeavourOS folder worked for me (i.e. I successfully rebooted) so should be fine.
Yeah this was actually mentioned somewhere in your grub to systemd-boot guide thread I believe, so I was able to do that earlier, I just wasn’t aware that there was more to potentially remove. But it’s all good to learn a little bit more today, thank you.
Since you mentioned this, I did have this issue of my system still trying to boot into grub even after removing it, causing failure. Had to manually remove the entry from efibootmgr.
It was a issue for some users that even with the grub to systemd-boot change that not all BIOS would update or “honor” the new boot order (or something to that effect), so like in my case, after switching, I had to reboot into my BIOS and change the boot order. Then after a successful reboot, I had to use efibootmgr to then find and delete the entries of grub that were left behind and all has been well since then.
