Wrong. Wrong, wrong, wrong. Please use an acceptable means, as shown in the Garuda Wiki. Rufus used to never work with Arch-based distros, and only does so now if the user just happens to choose the right settings.
Really, there’s no sense proceeding further until you re-write the ISO using an acceptable method. Here’s the link: System requirements & notes | Garuda Linux wiki See: " * To burn the iso to your thumb drive use our Garuda Downloader application, dd (Etcher, Imagewriter, …) or Ventoy
I note that the Downloader uses Rufus only because it is tiny, according to the Wiki. And the Downloader, according to its author, uses the correct settings.
I don’t know whom this “Rufus” character is but from a Linux perspective, I’d like to kick his “tiny” ass.
Anyway, the point is to start with a known-good image written to a known-good media using a known-good method. It doesn’t get any simpler than that. Then, if you still have problems, you’ll know not to troubleshoot in that direction.
