Note that this will definitely need to be tested, confirmed, and if confirmed written in the WIKI or download page, that RUFUS can NOT create Manjaro USB anymore, since its update where it doesn’t have the DD option to manually select (it is now an automated process).
So that may be new, because from experience, mine and others, after writing Manjaro ISO with Rufus, it boot to a grub error. It was working great two years ago, then it stopped working after an update like last year.
