@PauloCereda I don't really know what that means. But you have to like the wiki to use Arch. Here's
my first thread on their forums. Note that neither I nor they start out with any idea that an obscure requirement for Fat-32, ignored by the vast majority of firmware, is causing boot to fail. So this was never going to be a quick and easy question. But I'm a new user so both they and I assume that I've missed something.
