Invisible BootCamp Partition I can't access nor delete!

So to start with, I'm trying to install Windows 10 from a usb onto my computer with bootcamp (i use OS X elcappitan). So i followed the normal steps to install windows 10 through bootcamp like getting the iso file onto my usb (which is 8gb) and making the partition for it. But after going through this process, (and once i open up the windows 10 installer) i get to the part where you have to choose your partition to install windows 10 on and i don't see the "BOOTCAMP" partition there.

So i cancel the setup and return back to my main user and when i enter Disk utility, EVEN THERE, i don't see the partition Bootcamp made for me! It stinks because i put a good 90GB out of my 500GB hard drive into this partition.

One thing is that when my bootcamp was just about finished the creation of this partition, i got a message for a split second saying something like "Your mac has/is restarted unexpectedly" or "for no reason". It wasn't there long so i didn't catch everything but i feel like maybe my mac restarted for "some reason" during the last seconds of the creation of the partition thus making the partition incomplete and/or currupt? If so, and because of this my 90GB partition is invisible, how would I be able to find it and remove it to do a fresh reinstall?

This is how my main hard drive looks atm... its literally saying that my Macintosh HD occupies 100% of my 500GB hard drive, yet when you look at how much it actually occupies, it says it only occupies 409.53GB of space! This proves that the Bootcamp partition is STILL taking up space on my hard drive but at the same time, not showing it. My main goal would be just to remove this 90GB bootcamp partition entirely.

Im very annoyed with this and have basically spent an ENTIRE DAY trying to fix it myself with other, similar, online solutions. I hope someone could give me a solution or even just something to try to do to fix this :/

Thanks for reading my report.
