Repartion Bootcamp Drive

I installed Windows 10 with Bootcamp and allocated too much space, so I don't want to Windows keep all of that storage, so with a MiniTool Partion app I cut of the free space and made it to an other disk (because if I leave it unallocated Disk Utilty will still add it to the Bootcamp drive, so unallocated space is only available in Windows) and now inside Disk Utilty I reformated the disk so OS X can see it too and I can also use it like a seconday drive but there are no way to merge is with the main drive like I could used to be, why is that? Thankyou for the help and sorry for my english...

MacBook Pro with Retina display, OS X El Capitan (10.11.6)

There is no way to do what you are asking without reformatting.

In order to join two partitions, they have to be consecutive.

You cannot join the first (the mac partition) to the third (the one you carved from the bootcamp, which is the second).

You can always clone the mac partition to an external drive and then clone it back.

There used to be a tool that did the same for a windows partition (winclone, I think) but I never used it.

In any case, if you choose to reformat, it is a good idea to reformat as one partition and make a clean installation (which creates the "recovery" partition for you) before you clone the mac partition back; then apply the bootcamp to create the windows partition as desired, and finally clone back or install windows.

Please post the output of

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

It may be possible to use mergePartitions and then rebuild Recovery HD to make it a contiguous OSX partition. The "sudo" will prompt you for your password.
