How to fix Bootcamp after partition resize?

Hi, I recently resized my Bootcamp partition, not realizing that it would make it unbootable. Is there any possible way to fix te partition? It still shows up in Disk Utility.

MacBook Pro, OS X El Capitan (10.11)

For the link, do you want me to follow the steps? If so, I want to make sure everything is fine with my Terminal Outputs as I don't want to mess anything up by doing something I shouldn't. Thank you for your help so far!
