Question: I'm new to guitar. I don’t really understand the tuning and its relationship with music notes. Can someone explain how I can get my guitar tuning to

F, Bb, D, F, Bb, F (Capo on 1).

Answer: 
### Frame challenge: As a beginner, you definitely shouldn't

Using altered tunings is a common technique for advanced guitar players. When you've been playing several years and you're used to finding different chord forms all round the neck, you're probably ready to think about trying alternate tunings.

As a beginner, you simply aren't. You have no intuitive understanding of where to find notes around the fretboard. You don't understand the basics of how the instrument works. You haven't owned your instrument long enough to have any basic motor control in your fingers to play chords consistently and clearly.

As a beginner, work with beginner-level material and build your skills up. You didn't think up this tuning on your own (for reference, it's open A tuning with capo 1) so you must be working from some more advanced book or song and sheet. You need to drop this for now and go back to stuff which is in your ability range.

In a couple of years, if you put in plenty of practise, maybe you'll be ready to pick this up again. If you throw yourself against stuff like this right now, I guarantee you won't get anywhere with it, and I'll give good odds you won't still be playing in a couple of years because you've got frustrated with it. Don't set yourself up to fail.
John's answer is spot on. But I question why one would want to tune down a bit only to use a capo to bring it all up a semitone. That difference won't particularly affect the tension of the strings, so why not simply tune open to what is effectively B♭ open tuning? Maybe this doesn't answer the question directly, but - it does solve OP's problem!
