Ok, today a new problem came up and I think this one is beyond my knowledge to solve.
After setting up the system on my SSD (Samsung 850 Pro), and after I made my RAID 0 appear again, I installed windows 10. When I entered in them, all my drivers were there:
1 SSD, 5 HDD and a newer M.2 which I recently bought to replace my RAID 0 in sometime. Everything seemed to work as intended. I started install drivers, you know, chipset, audio, lan, GPU, PSU etc... Somewhere there, after some reboots, my m.2 disk dissappeared from my system. It is not in Device Management, and I cannot see him in Bios too.
My BIOS settings were Sata > RAID, NVMe RAID Mode > Disable, CSM > Disable, and everything else that has to do with NVMe Sata in BOOT Meny Enable.
If someone can help me figure it out that would very helpful after almost 24 hours I am trying to do everything work again...
Edit: If I choose CSM > Enable, then BIOS can see M.2 but windows not. If CSM > Disabled BIOS cannot see M.2 neither windows 10. I am losing my mind here, as it was there the first time I entered windows...
