Hi I have successfully Installed Windows in NVMe, now i have one more question since i was using my SSD 2.5 already in my system but whenever i m using both Hard drive NVME and SSD, it goes first to SSD not to NVME, how can i enslave the SSD drive or do i have to put usb key every time for bootloader?

as stated , for the z800 you must use DUET/REFIND ver 2015

have you created the duet/refind usb key? it's a very simple process and it walks you through the 4 steps to create it

next, select any motherboard usb port on the z800 (do not use usb add-in cards)

set the z800 bios to boot from usb first and save

reboot, the usb key should load and show you a screen asking which usb port  has the duet/refind key, try them one by one

till it hits the correct port/key, which will be visible as it will now show a different screen

now insert the windows OS usb install key reboot and the duet key should boot,.. load the nvme code and then pass the boot to the windows install key at this point the OS install will now see the nvme drive as a device it can install windows on

let it install, and when it loops back to the beginning of the os install, remove the win usb install key reboot and the win os install will continue off of the nvme drive
