how can i fix my hard drive while booting?

This question is in the category Powerboats - Desktop computers will be best

You do not say the make & model (not too important)

You do not say the Operating System (somewhat important)

You do not say what "too long" means - does it never boot up or does it just take a long time - how long?

Perhaps a new question will get a more sensible answer.

Good luck...
