    Need help with setting up mirror

    I have a workstation with 2 SSDs and I would like to set up a mirror (RAID1) with dynamic disks. This was very easy in MBR mode. Unfortunately I am in UEFI/EFI Mode and things are more difficult now.

    I am looking into the Microsoft documentation but theirs is based on another operating systems (Windows Server?). So, they have a different number of partitions and sizes.

    Could someone help me out with the settings for Windows 8. I'd like to mirror the drive and both should be bootable.

    Problem: Microsoft documentation differs from Windows 8 default installation as I will show.

    First things first:

    The attachment shows the Windows installation in disk management console. All partition have been setup automatically during installation.

    Secondly, the Microsoft documentation: "How to establish and boot to GPT mirrors on 64-bit Windows"
    How to establish and boot to GPT mirrors on 64-bit Windows

    Now, here things get tricky as Microsoft's disk configuration looks like this:

    DISKPART> List partition

    Partition ### Type Size Offset
    ------------- ---------------- ------- -------
    Partition 1 System 204 MB 32 KB <---- EFI PARTITION
    Partition 2 Primary 4996 MB 204 MB
    Partition 3 Reserved 32 MB 9 GB <---- MSR PARTITION
    Windows 8's looks like this

    [DISKPART> list partition
    Partition ### Type Size Offset
    ------------- ---------------- ------- -------
    Partition 1 Recovery 300 MB 1024 KB
    Partition 2 System 99 MB 301 MB <---- EFI PARTITION
    Partition 3 Reserved 128 MB 400 MB
    Partition 4 Primary 111 GB 528 MB
    For you see, not even the number of partition matches. Could someone help me with creating the bootable mirror please?
