Q: BOOTCAMP partition boot problems
Hi, I have seen a few posts that are very similar to mine, but I cannot seem to get to the bottom of this issue. Here is the background on what happened:
I was running El Capitan on a single OS X partition and decided to run Boot Camp Assistant and install Windows 10 on a new partition. This worked perfectly and I was using Windows and booting back and forth. I then decided that I would like to create a new partition to easily share files between the 2 OS's using a Fat-32 file system so that both OS's could have read/write access. I did this with Disk Utility on the Mac side and everything seemed to go smoothly. Also, I did not touch my BOOTCAMP partition, but took all the space for the new partition from the Mac side. Everything seemed fine.....until I tried to boot back into BOOTCAMP. Now this partition is not recognized as bootable, though it is accessible from within the Mac side and everything seems in tact.
I ran the diskutil list command and here is the output:
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER

My theory was that because the BOOTCAMP partition moved from 4 to 5, this somehow confused things. I decided that I didn't care any more about having the shared partition, so I erased it. I then tried to delete this partition, but I am unable to do this using Disk Utility in regular or recovery mode. I have tried unmounting and then deleting in both modes. I have scoured the the internet looking for a solution and I am completely stuck. This seems like it should be a super simple fix, but it's frustrating that I can't figure it out. I don't think I have damaged or corrupted anything and I just need to be able to boot into Bootcamp.
PLEASE HELP!!!
Thanks in advance!
MacBook Pro (Retina, Mid 2012), OS X El Capitan (10.11.3)

Can you use Re: [Help] Can't boot to windows (8.1) after resizing partition as a reference and run the steps? You will no longer be a able to see OSX partition from Windows after these steps.
