Thank you kindly for the guide.

Frustratingly, I am having problems...

http://www.legitreviews.com/images/reviews/1620/p67a-ud7-b3-bios-10.jpg

This is pretty much how my BIOS looks - however, 2nd from the top I think it's on IDE, so, I change it to AHCI - save, reboot.

BIOS error appears and I have to revert back to be able to proceed to login to windows....

Any suggestions?

After you change your Sata mode you need to boot into safe mode and then restart and you will be set

Sean, thanks for the great thread. I'm working on this but in a different way.

I just installed Win 10 Pro 64 to a Samsung 950 Pro NVMe on my Asus X99-A. SATA was in AHCI mode at time of install. I am now attempting to switch to RAID for a couple of other drives that have been freed up. I tried your method for Win 8 but to no avail.

I uninstalled IRST > uninstalled Samsung NVMe > Safe Boot > Change to RAID in BIOS > Will not boot to Safe Mode, I end up back in BIOS.

I was hoping that sense the 950 is controlled by the NVMe it would not be an issue. Do you have any suggestions for this configuration?

Win 10 installs really fast on this drive but I'd rather not have to reinstall Windows.

Thanks much
RogerC

Quick recap of system and goal.

System; Asus X99-A – 5930K – G.Skill 3000 16GB – 840 Pro 256GB (OS) – 850 Evo 500GB (programs) – Windows 10 Pro x64

Purchased Samsung 950 Pro 256GB NVMe drive and fresh installed Win 10
Two weeks later purchased a second 850 Evo 500GB to run RAID0
I needed to change SATA mode from ACHI to RAID in BIOS hopefully without reinstalling Windows.

Successful steps as follows;
In Run prompt type msconfig
On boot tab tic Safe Boot and leave Minimal set
Restart

Enter BIOS

Advanced Menu
--PCH Storage Configuration
----SATA Mode Selection [RAID]

Boot Menu
--CSM (Compatibility Support Module)
----Disable (you will get a warning, click OK)
--Secure Boot (insure set to Windows UEFI Mode)

Save & Exit. It should boot you into Safe Mode. Go to Run, type msconfig and on General tab tic Normal Startup. Now reboot. You should be up and running with SATA mode set to RAID.

Added bonus of disabling CSM is that POST no longer licks itself for 40 seconds before it starts to load Windows. Boot time is much less.

Based on the post above, I am assuming the instructions for Windows 8 to Change to AHCI from RAID mode should work the same way in Windows 10, correct?

Before I give it a go, I am wondering if doing this different from doing a clean install. From what I have read, windows intentionally disables certain drivers when choosing a STATA mode in BIOS so that it does not use unnecessary resourced during startup loading those drivers. If I follow these steps, does this mean I will have two sets of drivers and then be able to SATA modes in bios anytime I want without going through those steps again? And will this also impact my computer during regular use, like longer startups or anything else?

Also, on the last step (Your system should boot into windows fine and you can install your AHCI or RAID driver.), it is a little confusing. If I already successfully booted into Windows after switching SATA modes, why do I need to install additional drivers?

Thanks!

This guide worked for me to change from RAID to AHCI. But it should be added that all control sets should be edited, not just CurrentControlSet to be 100% safe.
