If I have an exam tomorrow and I said the following:
- I have to study hard because I really don't want to take the exam again.
- I have to study hard because I really don't want to have to take the exam again.
What's the difference between 'don't want to' and 'don't want to have to?'
I'm not sure but I think 'don't want to' here simply talks about what you personally want and not. And 'don't want to have to' means that there's something (certificate) for which you'll have to retake the exam if you fail.
