Unable to select a drive to install windows when NVMe's are in a RAID array.

[Promentum]

I am currently making a server and using the ROG Strix Z790-H as the motherboard with a i7-14700k as the CPU. The bios is in version 2.22.1286 and every guide I have seen and followed have additional settings like:

SATA config
m.2_1 PCIe RAID support
m.2_2 PCIe RAID support

I do not have these we have tried installing additional drivers to try to get raid working, and we have set up via an temp drive to then try read the RAID from inside windows "drive formatting" menu.
Every time I try to boot after making the RAID (that I can see in the bios is there) when it comes to the select drive it shows nothing and prompts me to go to drivers which there are none of and we have tried hundreds. When I boot after deleting the RAID it will let me select to any of the 4 NVMe's.

Not sure what is happening, Please advise.

You probably need to point the IRST drivers to the installer during system installation.

Note 1: in the past, Intel included a floppy disk version in IRST packages, and this floppy disk version had to be used during system installation. Nowadays, the “floppy” version has to be extracted from the EXE file.

Note 2: this was the case in 2023, and I haven't checked it since and don't know how it is now.

I don't know how to edit the previous post.
