[Z790M-ITX WiFi] Can't install Windows on NVME SSD

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

   I have ASRock Z790M-ITX WiFi. I have just one SSD - it's M.2 WD Black SN850X NVMe.
Whenever I try to install Windows 11 (from pendrive), I get info that no drives where found, and I can install drivers to potentially find drives.

I tried following https://forum.asrock.com/forum_posts.asp?TID=1236&title=how-to-install-windows-on-a-pcie-ssd, but no success there.

What I had tried (and failed):
1. Update BIOS to latest stable (v10.05)
2. Update BIOS to beta (v11.05)
3. Enable VMD mode in BIOS - when I did that, I was able to select Intel RapidStorage driver during Windows installation. Unfortunately, selecting that driver, does not make the SSD discoverable
4. Enable VMD with Global mapping in BIOS - when I did that, I was able to select 2 drivers (one with "Management") - selecting them does not help
5. Enable CSM and setting all options to "UEFI only"
6. Disable Secure Boot
7. Disable SATA
8. Boot into Fedora Linux and format my SSD as NTFS - Windows installer still doesn't see it

Is there anything else I could try?

	SOLVED. In my case: I was creating USB card with Win 11 from Mac using dd command in terminal and before I was formatting it in MS-DOS (Fat32) using scheme GUID. What I changed: Formatting MS-DOS (Fat32) using scheme Master Boot Record. The I just copied all files from iso to this formatted USB flash drive. That's it! It worked. After w days & 17+ hours of searching. Cheers! P.S.: in my case I didn't have files more, than 4Gb. If you have - check youtube for Wimlib app
