Bootcamp Partition Missing

Hello everyone, I accidentally ejected my bootcamp partition that was on my desktop and now it is no where to be found. It doesn't even show up in my disk utility. Any ideas and why/how this happened and is it fixable?

I have 2015 rMBP 13 running El Capitan.

I made an appointment with the Genius Bar tomorrow but it would be nice if I can get this fixed before then.

Any information is greatly appreciated!

Thanks.

 

I have tried restarting it several times. The bootcamp partition doesn't populate when I hold option at boot either. I'm guessing worst case scenario would be having to reformat and reinstalling everything.
