Creates a Microsoft Reserved (MSR) partition on a GUID partition table (GPT) disk. Syntax: CREATE PARTITION MSR SIZE= OFFSET= ...

    Creates a Microsoft Reserved (MSR) partition on a GUID partition table
    (GPT) disk.

Syntax:  CREATE PARTITION MSR [SIZE=] [OFFSET=] [NOERR]

    SIZE=    The size of the partition in megabytes (MB). The partition is
                at least as big in bytes as the number specified by N. If no
                size is given, the partition continues until there is no more
                free space in the current region.

    OFFSET=  The offset, in kilobytes (KB), at which the partition is
                created. If no offset is given, the partition is placed in the
                first disk extent that is large enough to hold it.

    NOERR       For scripting only. When an error is encountered, DiskPart
                continues to process commands as if the error did not occur.
                Without the NOERR parameter, an error causes DiskPart to exit
                with an error code.

    A basic GPT disk must be selected for this operation to succeed.

    Caution:

        Be very careful when using this command. Because GPT disks require a
        specific partition layout, creating Microsoft Reserved partitions could
        cause the disk to become unreadable. On GPT disks that are used to boot
        Windows, the EFI System partition is the first partition on the disk,
        followed by the Microsoft Reserved partition. GPT disks used only for
        data storage do not have an EFI System partition, in which case the
        Microsoft Reserved partition is the first partition.

    Windows does not online Microsoft Reserved partitions. You cannot store data
    on them and you cannot delete them.

Example:

    CREATE PARTITION MSR SIZE=1000
