BootCamp Partition - Lost Windows Partition MBR
I have been using BootCamp on my mac for years, with no issues. About 6mo ago, I noticed I needed more space on my Windows Side, so I resized my partitions... everything seemed to go fine... I am running windows 10 on the Windows side & El Capitan on the Mac Side...
I really do not use the Mac side barely at all, but I want to be able to have both, the best of both worlds...
So basically I went to go onto my Mac side yesterday & rebooted into the Mac side, no problems! Did what I needed to on that side & then went to Restart in Windows Partition & there is NO windows Partition anymore in the Startup Disk ... It just has the Mac OS X ... I am guessing I never saw any issue before this because I never went to the mac side...
I really don't want to have to do a FRESH install of both again... if I can help it...
IS THERE ANY SOLUTION or an EASY FIX ( I know I am reaching... hoping & praying ) to get the MBR back in some way? that is what it looks like as I was searching around...
I tried to do what this article said, but nothing changed... http://nerdr.com/bootcamp-partition-lost-repairing-mac-partitions/
When I restart & hold down the OPTION key, 3 choices come up, Mac OS X / Recovery / Windows, when I choose Windows it says, MISSING OPERATING SYSTEM...
I want to be able to at least get the data off the drive & really don't want to pull my iMac apart to get to the hard drive & then if the data is even there??
Will the data be there?? in Disk Utility I can see there 500gb of Untitled, but I know that was my Windows Partition, before I ever tried to resize... the resized partition should be 750gb I think...
Anyway, I hope someone can help...
This something else I ran, hopefully it will be helpful to someone that can read it & know what it is saying...

One other thing i did today was upgrade to El Capitan, thinking that would help matters... the disk utility looks different now, BEFORE El Capitan I could see the Disk0s4, now I get a graphic like this one I have embedded ... I can see the Windows partition, but now it doesn't have the Disk0s4 anymore on the left... now it is ALL TOGETHER...
