I came across this question about dual-booting and windows not being recognized by Grub, which I'm fairly certain is a duplicate question, but I can't seem to find the canonical question that actually answers it, just a whole bunch of similar questions without answers that are often marked as duplicates of some other question equally without answer (or only limited useful ones).
Does anyone know a question that has some extensive answers, so we can mark it as a duplicate of that question?
P.S. I would normally ask this question in the chat, but it never logs me in, but that's a different issue;)
