Windows 10 lost boot loader and now can't bootcamp in

[Samuel_z]

Hello everyone,
First time poster and in need of help

I have a MacBook Pro (Retina, 15-inch, Mid 2015) running 10.11.6 (15G22010), and have bootcamp running with a windows 10 partition.
I also have Parallels running for when i need to quickly jump into windows whilst Mac side.

As of Monday night, I am unable to boot into the windows portion via the Option key at boot and select drive.

No issues getting into macOS, and Parallels is working fine.

A little google has pointed to the windows boot loader being removed/corrupt.

I looked in Disk Utility and can see the bootcamp partition, but when selecting info, i can see it says
BOOT : NO

Im very perplexed and could really use some help.

Thanks

Actually, i am know wondering if i need to reset the Macs GPT and/or MBR.

Would anyone have any help on how to do that?

When did you install 10.11.6? Have you made any other updates or changes to your OS?
