While trying to create a dual boot, I uninstalled Intel RST in the Device Manager. Big mistake, now I have a blue screen when booting my Windows 11.

I discovered later that I needed to press Ctrl+S in the BIOS to just disable Optane with RAID on the SATA mode, like on this picture of documentation: https://us.v-cdn.net/cdn-cgi/image/fit=scale-down,width=1600/https://us.v-cdn.net/6029997/uploads/editor/0o/0qmnwbrlxjdd.jpg

I tried all SATA mode but my Windows still wont start without Intel RST driver..
I reinstalled Windows 11 on another partition to try to recover the main one, but I don't know what to do. Is it possible to reinstall Intel RST from one Windows 11 to another ?

My pc is an Acer Nitro AN515-55, my config is: https://www.driverscloud.com/en/configuration/smkrlr7jrk4-1/summary

  • At what stage of the boot do you encounter the blue screen? Can you boot into Command Prompt?

  • Indeed, Intel RST or similar "RAID" modes managed by the firmware aren't (yet) supported in Linux, reason why everywhere it is said to disable (change drive mode to AHCI) it but also to install AHCI support in Windows. If you want to dual-boot that's how it'll have to be. You could've just "repaired" the current Windows installation as that would've installed AHCI support. Commented Jan 30 at 16:00
  • @harrymc I have the choice of the boot between my Windows, and if I select my old Windows, I'm able to go to "repair" and select Command Prompt !

  • Download the Intel RST setup as in here, boot to CMD and try to run the installation.

  • I tried to do this, and also unzip the .exe and install the .inf using pnputil but nothing works. I don't know if I am on a windows or on the good windows when getting on command prompt. I can get here by letting the PC have a blue screen. Then when it restart, I have Automatic recovery > Advanced options > Command Prompt. But it launch a command prompt on disk X: that don't exists normaly. I need to go myself on my disk E: then install the drivers, and I think it's not the on any windows..
