I flagged it as duplicate and left a comment saying that reposting questions is a bad idea, even if parts of it were changed.
However, the question also has an answer, saying that "this code helped me" (even though it is a link-only answer).
What would be the best practice for handling this question? My best guess would be:
- Close the question as duplicate.
- Migrate the answer.
- Edit the answer to include the GRUB code.
