Windows 10: Unable to change from Intel RST (fakeraid) to AHCI

For various reasons, I am attempting to change my system from Intel RST to AHCI.

I followed the various guides I have found on the internet to go about this.

Here was my process:

1. cmd: bcdedit /set {current} safeboot minimal

2. regedit: changed Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride "0" Dword value from 3 to 0

3. restart computer into UEFI firmware settings

4. change from Intel RST to AHCI.

After following these steps, I get a message about starting up automatic system repair. I then get a classic blue screen. Starting up cmd from there puts me on X:\, not C:\. attempting to cd C:\ gives me an error that it is inaccessible.

I then opened regedit from cmd, and checked the Dword value that I changed earlier. Despite my original changes, this value was still set to three.

I am running a Lenovo Legion Y530 with a 2TB HDD and 16GB Optane.

Thanks!

Intel RST AHCI driver for ICH10R?

They hide stuff from you, probably to try and get you to upgrade. Intel's site says nothing about RSTe 4.2 or 4.3 drivers being supporting on anything other than C200 and C600 chipsets however, they work incredibly well on X79. On the same token, the latest RST drivers (for RAID,) also seems to work on my X79 in RSTe mode.

Needless to say, I think Intel needs to consolidate RAID drivers into a single package and AHCI drivers into a single package as opposed to trying to support several different versions for several revisions of the same damn thing running probably the same damn software.

I'm glad you got it to work but, I would have attempting forcing the installation of the newer AHCI driver. The first time I used the C200/C600 chipset RAID drivers on my X79 board, it didn't simply "accept" it and I had to force it to install. Ran great but, it wouldn't just take it.

So does Intel: https://downloadcenter.intel.com/download/22194/Intel-Rapid-Storage-Technology-Intel-RST-RAID-Driver

All prior releases of RST should be in this list: https://downloadcenter.intel.com/product/55005/Intel-Rapid-Storage-Technology-Intel-RST-

 

Intel RST AHCI driver for ICH10R?

Yep, something I have found is Intel RAID drivers as they are called are also their AHCI SATA drivers, so they are perfectly safe to install even in non-RAID systems.

 

Intel RST Driver

Okay, and it says that the best driver for MY chipset is 15.5.0.1051 which is listed on that site... and besides, I only use the driver itself, not the full RST software.
