You have El Capitan, so we need to disable SIP.

1. Boot into Local Recovery (Command+R).

2. Start Utilities -> Terminal.

3. Type csrutil disable in Terminal and press Enter/Return.

4. Type csrutil status.

5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.

Please ignore the i386 MBR error message, but not any others.

sudo fdisk -e /dev/disk0

setpid 4

Reboot and check if you can see the BC Volume and files in the volume using Finder. If you can, use System Preferences -> Startup Disk, click on the lock icon and choose Bootcamp and click Restart.

Please backup OS X, Windows and create Windows System Restore point.

Apple does not support resizing Windows when a MBR/BIOS is used. Your Mac does support EFI boot for W10 which can help but it requires re-installation. You can also use third-party cloning software like Winclone or Camptune.
