Missing BIOS Options ASUS PRIME Z690-P D4 no option to change SATA mode

So I just ran into this same issue with the same motherboard, ASUS PRIME Z690-P D4, but with only a single Samsung 980 Pro installed. The 980 Pro, as a single drive, was being forced under RAID and did not show up as selectable for a Windows 10 64-bit install.

Go to: Advanced\System Agent (SA) Configuration\VMD Setup Menu

By default VMD is Enable VMD Controller [Enabled]. Set Enable VMD Controller [Disabled]

This will allow the bios to configure the drive correctly and allow windows to be installed.

VMD is for use with Intel Xeon Processors. The 12700k installed in not a Xeon processor, unless I'm mistaken.

Yep $120 was the price, that's an excellent point though, I'll try again tomorrow, hopefully things workout better for me. I brought my whole PC in today and they told me to just bring the motherboard inside to replace it, so I asked if I can disassemble it, and they were like yea, as long as it's not in the store so I had to disassemble it in my car...

I literally found my login just to say thank you for this information. I have been working on my new PC for HOURS and cannot figure out why all my drives were being forced into raid without my doing and without any option to take them out on the bios.

I updated the bios, I attempted to reinstall windows on an already perfectly good install, I thought my Samsung 970 was bad, I thought my other SSDs were bad, I thought I got a bad z690, I thought I shorted something out. Googling different variations of my issue for hours, until I found this thread.

Thank you so much, turning this stupid setting off fixed everything.

So I got a new motherboard, and I got my PC up and running perfectly. However, then came the issues I turned off my computer for a while and when I came back to turn it on I got an error with Post, it wasn't anything big I forgot to set my CPU fans controller in the BIOS to ignore (since I have an AIO) However, thus board is also missing the Sata Mode Configurator🤦🏽‍♂️

I booted back into Windows hoping it wouldn't affect anything but of course, the Inaccessible Boot Drive error came back and my Boot Drive is stuck in RAID again...

Thank you for your swift response. I can't see any of the other SATA modes in the BIOS as those options to even see them are also missing. But it is as you said, that AHCI, SATA, and RAID should all be selectable options. But they don't show up on my boards BIOS at all, and I've cleared the CMOS multiple times to see if that would fix the issue but to no avail.

I purchased this motherboard and CPU from Microcenter Yesterday and built it that night, my very first boot I went straight into Windows no problem without any updates to the BIOS and or Windows, since the drives I had were from my previous computer it was almost like nothing changed. But I then reset my PC to look at the BIOS options to enable XMP and use Asus' EZ Tuner, without touching a single advanced setting. I booted back up and ran into a blue screen saying Inaccessible Boot Drive. I thought Windows was the issue at first but after much troubleshooting I realized that my drives were not being picked up by Windows since they were now all of a sudden being forced into a RAID configuration.

I reached out to Asus and cleared the CMOS a few times and saw that my drives weren't even being recognized as regular drives anymore but they were under the RAID controller I was able to see that with the initial Post screen after clearing CMOS, because of this it's almost like Windows has no available drives to boot with. The only drives this motherboard is now reading correctly are external USB drives and I know this because I tried booting windows from a USB, but I can't install it since none of my internal drives are recognizable.

Asus has escalated the case and said they will get back to me within 48 hours, but I really need my PC working again so I'm going to take my whole system to Microcenter tomorrow and possibly do a motherboard swap since I literally bought it yesterday.

Please, I'd love to hear yours or anyone else's thoughts on this.
