Unable to install Windows to NVME RAID 0

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I was trying to set up both of my NVME drives in RAID, but it won't allow me to install Windows. I used ASRock's tutorial (https://www.youtube.com/watch?v=qg1Vvh67Efw) and was able to create the RAID config perfectly. 

Its just that when I loaded the Windows installation, the RAID config showed up fine, but Windows says, "Windows cannot be installed to this disk. The computer's hardware may not support ootijg to this disk. Ensure that the disk's controller is enaled in the computer's BIOS menu." It says this even after I load the drivers from ASRock's website. 

I'm using an ASRock Z490M-ITX/ac with an Intel i7-10700k and two 512GB NVMEs. Literally the only thing different that what was shown in the video was that "Launch Storage OpRom Policy" was called "Use RST Legacy OROM" in my BIOS, and was already set to UEFI. I even tried factory resetting my BIOS, formatting both of my NVMEs, and retrying the same steps.
