  1. update the BIOS of your motherboard in BIOS itself via M-Flash

    Boot windows from the 960, if it´s faster after the BIOS update.

    did you install windows seperately on each ssds? One SSD installed at a time while installing windows?

    did you install the Intel Rapid Storage Technology Driver ?

  4. Did you install windows in UEFI mode?
    "Intel® RST only supports PCIe M.2 SSD with UEFI ROM,
    does not support Legacy ROM." (source: manual of MSI)

    Is the M.2 SSD installed in the M2_1 or in the M2_2 slot?

    in bios there is an option UEFI Rom or legacy ROM
    set "UEFI and Legacy BIOS Mode“ to „UEFI only“

    if the BIOS was resetted (load standard defaults in BIOS), UEFI should be fine there

    use the microsoft media creation tool to get a bootable usb flash drive, boot the flash drive in UEFI mode and install windows

    eventually you will have to format the usb flash drive into GPT and use Rufus to install windows in uefi mode
