This is what you need. The following command

a. changes the size of Macintosh HD to 125g

b. creates a BOOTCAMP partition 60g Free Space

c. creates a SHARED 40g FAT32 (the 0g means the remainder)

Please post any error messages

diskutil cs resizeStack

You will need to create a large enough partition to accommodate both your Windows and the Shared partition when using BCA. Once the partition has been created, you will need to cancel the W10 installation, manually partition the single partition into two parts and use one part for Windows and the second for your Shared file system.

Please post the output of

diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0

There may be another option based on the output of these commands.

Yes, it is clear. Disk Utility will not do certain types of partitioning, but the command-line diskutil will let you create more elaborate partition schemes.

In the following command, you can create a partition for Bootcamp (part1) and a shared partition (part2) in one command when reducing the core storage volume. This also mandates an EFI installation of Windows. (MBR installations using this method can break much more easily and are very fragile).

diskutil cs resizeStack

Usage: diskutil coreStorage resizeStack

        lvUUID|MountPoint|DiskIdentifier|DeviceNode [pvUUID] size

        [part1Format part1Name part1Size part2Format part2Name part2Size

         part3Format part3Name part3Size ...]

Resize both a logical volume and one of its underlying physical volumes in a

single operation. A single physical volume is always chosen for the underlying

shrink or grow, even if the logical volume's logical volume group is backed by

more than one physical volume. If you do not specify a particular physical

volume, then one is chosen for you. Note that if this is a grow operation,

this verb is limited by the physical volume's partition's room to grow.

Specifying zero as the size asks for an "automatic" grow-to-fill operation.

If this is a shrink operation, you can optionally request that new partitions

be created in the newly-formed free space gap in the partition map.

Again, note that this only resizes one of the underlying physical volumes; if

you need more sophistication in managing your topology, you should use the

separate physical and logical volume resize verbs.

Example: diskutil coreStorage resizeStack

         11111111-2222-3333-4444-555555555555 10g JHFS+ New 1g

You can see some variations of commands used in OSX and Bootcamp discussion .

So first i have to type this:
diskutil cs resizeStack

And then this ?? ( here i got lost)

        lvUUID|MountPoint|DiskIdentifier|DeviceNode [pvUUID] size
        [part1Format part1Name part1Size part2Format part2Name part2Size
         part3Format part3Name part3Size ...]

if you can tell me in more simple way because I'm not familiar with command language

BTW I created a booted USB for windows 10 , so I guess I just need to finish partition the 2 parts ( Bootcamp + Share ) and start the install progress .. ( is this correct ? )

The command is a single command and it creates two additional parts. It is meant to be used just once. Now you have a 125g Free Space part, but no shared part. Can you post the output of

diskutil resizeVolume disk1 limits

In Disk Utility can you drag the size pointer and make the Macintosh HD occupy the full disk space?

This is what you need. The following command

a. changes the size of Macintosh HD to 125g

b. creates a BOOTCAMP partition 60g Free Space

c. creates a SHARED 40g FAT32 (the 0g means the remainder)

Please post any error messages
