Q: unable to boot using bootcamp after creating new partition

Hi! I recently formatted my macintosh HD partition and reinstalled OS Captain. After that I am unable to boot using bootcamp. I can still see Bootcamp option in startup menu of system preferences. All files are also visible in bootcamp in finder. Please help to restore my bootcamp functionality.

MacBook Pro, OS X El Capitan (10.11.5)

    This is a non-standard disk partitioning scheme and does not work when Windows is installed using legacy BIOS.

     

    Can you use [Help] Can't boot to windows (8.1) after resizing partition as a reference and rebuild your MBR?

    Assuming your Mac has a legacy BIOS installation of Windows (version?), the steps are identical.

    W7 should be BIOS mode. What year/model is your Mac?

    Please use the same exact steps. W10 is not officially supported on your specific Mac.

    thanks again! Just one more question. When earlier i used to power on with option pressed, i used to get 3 options: 1 for MacOs, second for bootcamp and third for utilities. I dont see utilities anymore. What could be the issue?
