    Did someone find out how to Create a OSXRESERVED like partition on OSX?
    The little Partition that Bootcamp creates for installing windows.
    I need it so i can deploy that partition and put WinPE on it.

    Thank You:D

    EFI partition should be the partition you want.

    And recovery partition, hmm.

    You can create a new partition, and install boot loader inside it.

    But with the Bootcamp Assistant created Partition it works with WinPE, so there must be a chance to create a partition like this via Terminal. I just couldn't find out how, so i thought i'd ask here :D maybe someone figured it out how this works.

    :D I somewhat want to do the same, so I can try to install Windows PE for advanced maintenance tasks.
    There must be a way. But unlike Windows, which we have bcdedit and integrated VHD support to make the life a hell lot easier, Mac OS X doesn't publicly let us know where is the boot volume.
    I don't know how to view boot order under terminal, either. :(

    i found a way how to create the partition.

    You just normally create 2 new fat32 partitions 1 for Windows and 1 for WinPE

    But when you create these Partitions OSX is creating a MBR for the partition so that its Hybrid MBR with GPT (something like that o_O)
    When you successfully created those Partitions you need GPT fdisk (http://sourceforge.net/projects/gptfdisk/) to create a new protective Mbr.
    after you installed gptfdisk open up Terminal and give in these Commands

    - gdisk /dev/diskX
    - x //to enter expert mode
    - n //to create a new protective mbr
    - w //write changes
    - Y //confirm

    and then copy the WinPE Files to the WinPE partition and start from the partition.

    Tested under Yosemite and El Capitan.


    Here is what i did exactly:

    diskutil resizeVolume /dev/disk0s2 500G fat32 WINDOWS 0b
    diskutil resizeVolume /dev/disk0s2 498G fat32 WINPE 0b
    cp -R /winpe/* /Volumes/WINPE/
    gdisk /dev/disk0
    x
    n
    w
    Y
