Changing from the RST Optane driver to AHCI in an existing Windows 10

First of all, the system won't need a driver change to run Windows 10. Both AHCI and the PCIe drives are included in the RST Optane driver. It does both.

So upgrading to my NVMe SSD would merely mean disabling the RST Optane software and exchanging the NVMe Optane M.2 card with the SSD and it would (probably) work without any changes in the BIOS

With the RST Optane driver installed in Windows 10 the mechanical drive would be running off of the AHCI part of the RST Optane driver and the SSD would be running off the NVMe part of the same RST Optane driver.

My problem is that Linux installers don't like non standard drivers so the Linux installer doesn't see the Drive and so I would need to change the Windows drivers to AHCI and also the corresponding BIOS settings

My question is I found what looks like a good solution but I need a second opinion. It looks "too easy" and "to good to be true"



My windows loaded drivers:

Thanks in advance

Windows drivers are of no concern to Linux. In my case, I have an Intel NUC8i3BEH, which has an optane-compatible NVMe slot, which I use for an SSD, and a regular SATA slot, which contains an HDD. Both drives work fine under both Linux (Ubuntu 20.04) and Windows.

I found a note in the NUC specs document: In order to use supported RAID and Intel Next Generation Storage Acceleration with Intel® Optane™ Technology features, you must first enable RAID in the BIOS.

True, but I want to Dual Boot Windows 10 & Ubuntu

Which means I need to get Windows on the same driver as Ubuntu would use or I'd need to go through the BIOS every time I wanted to switch..... I'll admit it.... I'm lazy and I'd rather select the OS through Grub

I'm also not sure if Ubuntu will install right if a curve ball like weird Windows Drivers are thrown at it

These are exciting times for Linux. Graphics Cards manufacturers are actually taking Linux seriously and Linux drivers are now being developed for serious Linux gaming. And Steam is getting on board

So, I want to be able to install a game on Windows 10 and on Ubuntu..... Then compare/contrast

Thanks siepo

Didn't know Canonical had an Ubuntu discourse forum. Had tried Ubuntu Forums and that equaled Nada

Looks like what I need....

Well, wish me luck..... I hope I can preserve this current Win 10 install

Here Ubuntu installation on computers with Intel(R) RST enabled is another long story about Intel RST and dual-booting Windows and Ubuntu. It involves, among other things, making some registry changes before changing BIOS settings.

It worked like the proverbial charm

Windows 10 is now booting with AHCI enabled in BIOS and everything is now kosher for an Ubuntu dual boot





Again, Thanks!

A quick update.... Western Digital has great SSD software plus a custom version of Acronis disc cloning program (Acroniswd) and it even makes the new SSD the default boot....

It's alive......

Thanks, that's way simpler than this guide I got from Google:

1) Launch Command Prompt as Admin

2) Type this command and press ENTER: bcdedit /set {current} safeboot minimal

If this command does not work for you, try bcdedit /set safeboot minimal

3) Restart the computer and enter BIOS Setup.

4) Change the SATA Operation mode to AHCI from either IDE or RAID (again, the language varies).

5) Save changes and exit Setup and Windows will automatically boot to Safe Mode.

6) Right-click the Windows Start Menu once more. Choose Command Prompt (Admin).

7) Type this command and press ENTER: bcdedit /deletevalue {current} safeboot

If you had to try the alternate command above, you will likely need to do so here also: bcdedit /deletevalue safeboot

8) Reboot once more and Windows will automatically start with AHCI drivers enabled.
