Help Dual boot - Raid on or AHCI

Hello,

I have an Dell Precision 5530 2 in 1
Bios version 1.8.9
SSD M.2 NVMe Micron 1024Go

I want to install dual boot with Windows 10 LTSC and Ubutnu 18.04.3 LTS

Here is my problem, I selected "Raid On" to install Windows 10 and it works, but when i put my USB key to install Ubuntu, my SSD doesn't appear, I can only choose the USB key memory.

I tried to modify grub file with "nvme_load=YES" and it still does not work

I changed SATA Operation with AHCI, Ubuntu works and i can install it.
After installing Ubuntu, i restart the computer, Grub appears, i choose Windows but i have an bsod "INACCESSIBLE BOOT DEVICE"

-Raid On : Windows works but Ubuntu remains stuck on a purple screen
-AHCI : Ubuntu works but i have an bsod INACCESSIBLE BOOT DEVICE

I searched everywhere on the internet
I tried to find a driver for the disk
I also installed the last driver for my NVME Controller (Intel Chipset SATA/PCIeRST Premium Controlller)

Where is the problem ? 

Thanks for the answers
