Unable to install windows 11 on ROG MAXIMUS Z890 APEX

[mdg12v]

Hi,

I have ROG MAXIMUS Z890 APEX motherboard. I installed 2 Samsung Pro SSD to DIMM 2 slot. 
I see both m2 nvm devices under vme devices section in BIOS. 

But, when I boot from Windows 11 installation USB, it does not able to find devices. 
I have downloaded a lot of drivers from multiple places. As well as from motherboard official page. 

I have upgraded bios to the latest version. 

But nothing helps. The installer says "error installing driver" etc. 

Please help.

Thank you.

I would probably start with one new drive.  You could install it to the first M.2 slot, so you don't have to remove the heatsinks on the other slots.

Are you using a Samsung 990 Pro?

I will assume, you are able to boot into the Windows 11 install media but are unable to see and set the configuration of the install.

If you need to attach pictures from the Bios, you should be able to capture those to an external drive directly from the Bios page.

Have you partitioned the drives or are they "raw" - if not try partitioning.
