Bootcamp Corrupted

Ok, so I was trying to use boot camp for the second time because I wanted to change how much space. I tried installing it and in the middle while it was partitioning disk I shut down my laptop because I wanted to cancel it, then later that day I opened my mac to see that I can, in fact, select to windows after shutting my laptop down holding option, but when I clicked on windows it gave me an error that said "Your computer/PC needs to be repaired" and I got back to Macintosh and went to disk utility to see that there is no boot camp partition, I tried installing windows again and it was a fail probably because my corrupted boot camp windows is still in the computer, Somebody please come up with a solution. Thank You
