Welcome to the reason 99% of Linux distros remain so unpopular and both hard and unintuitive to use unless you’re tech-savvy. After those 5 minutes about 50% do it correct, the other 50% put a single character in the wrong place or follow an incomplete and bad guide and get stuck in boot. Or they’ll go and use an OS that’s more intuitive and more efficient for them despite probably also extorting them because that weird “Linux” thing is obviously only for nerds, who’re completely detached from the reality of most people out there not realizing that modifying core system configuration by hand that can make your device inoperable without any help from your operating system itself should not be the god damn norm.
