Installed Windows, OSXRESERVED partition still exists

So basically, I used Bootcamp in order to install Windows 8.1 onto my MacBook Pro. I also upgraded to Windows 10, but not sure if that has anything to do with the reason why it's not registering that Windows is installed? I installed the Bootcamp software onto Windows 10 too. But when I look at my partitions, the OSXRESERVED partition still exists. How am I suppose to remove it? I think that I read somewhere that removing it would also prevent the Windows partition to boot up as well.

MacBook Pro with Retina display, OS X El Capitan (10.11)

The process needs to be more robust, but it cannot handle all possible scenarios that a user can encounter.

OK everyone, this is easy. Don't think everything is impossible.

1. Launch up Disk Utility

2. Click on your Main internal drive (and not the partitions)

3. Click the Partition icon/button

4. When you see the pie chart, click on the OSXRESERVED partition in the pie chart

5. click the minus sign

6. click apply

I've done this a few times and my windows was fine after each time.

Hi there! I followed your instructions but alas, the minus button is grayed out. Any suggestions?

If you reboot, does the OSXRESERVED partition still exist? If yes, from macOS Terminal, post the output of
