What 0brand probably intended to say (which I agree with) was:
This thread looks like similar to Whonix starts first, but after first Screen - Blackscreen. Therefore please click Whonix starts first, but after first Screen - Blackscreen, read it, and then answer the questions.
You’re not supposed to answer other users questions on how to fix issues. Rather, the idea is that you answer the questions which were directed back to the user, which were asked by Whonix support, which were asked there by 0anon / 0brand.
