I resized my partition to increase my bootcamp drive few months ago on Disk Utility on Mac and after that I decieded to have more space on Bootcamp partition so I resized it again by set new size for Macintash HD but when I reboot my Mac and hold alt key there was no Windows option so I googled and followed this discussion: https://discussions.apple.com/thread/4144252 based on this answer: https://discussions.apple.com/thread/4144252#19071422, after I rebooted my Mac I saw Windows option but after select windows I get System Operating Missing.
here is current situation of my partions and disk:
