A:

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

    Please click on the (Show Details). Did you use EFI Boot or Windows icon from the USB to start the Installer?

    Please post the output of sudo fdisk /dev/disk0 . The ALLFILES FAT32 would have created an MBR, but let us confirm.

    And your GPT is

             40     409600      1  GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B

         409640  244865632      2  GPT part - 53746F72-6167-11AA-AA11-00306543ECAC

    so it does match. We need to delete the MBR, if we need to run the EFI Boot.

     

    Do you have Gdisk installed? If yes, then (do not enter anything inside the parenthesis which is an explanation)

     

    sudo gdisk /dev/disk0

    x (Experts menu..)

    n (create a new protective MBR)

    o (print the MBR)

    w (write)

    y (confirm write)

     

    Reboot and try your EFI Boot.

    1. Please back up OS X, Windows and create a Windows System Restore point.

    2. Can you post the output of

         diskutil cs list

    I can't see my OS X partition from windows.

    Your OSX Partition is a CoreStorage volume (disk1). There are no Windows drivers provided by Apple to read CS volumes. However, if you must see the OSX partition, the current state can be reverted.

      Revertible:            Yes (no decryption required)

    If you want to test, ,please run the following command.

     

    diskutil cs revert disk1

     

    We use disk1 which is the CS volume, not disk0s2 which is the underlying physical disk.

    Loner T, I see you have extensive knowledge concerning the topic, and I wish you could help me with a similar problem.

    fyi I'm on El Capitan.

    I installed windows 10 via bootcamp, without any external drives, on my 256GB ssd. I then used disk utitlity to create a shared partition by shrinking the OSX partition. After that, when I boot into windows it shows me the recovery screen, like Tamouh A's. As I said, I'm not familiar with the topic, so please, help me with each step.

    Thanks.
