    Enable RST in BIOS after installing in AHCI mode




      Windows 10 fails to boot when I enable RAID in BIOS. Please tell me how to install the "iastor" driver properly.


      Steps to recreate:


      1. Install Windows 10 with the AHCI drivers to a hard drive

      2. Do whatever (for 6 months +)

      3. Install RSP drivers and software from the vendor (ASUS)

      4. reboot

      6. Enable RAID in BIOS

      7. Configure two drives in stripe mode (unrelated to windows-system-drive)

      8. Boot


      What I expect:


      I can boot the system and access my windows-system-drive as if nothing hat changed.

      I can configure or format the newly created raid-0 with windows tools.


      What actually happens:


      Reboot at the  INACCESSIBLE_BOOT_DEVICE blue screen




      I get the notorious INACCESSIBLE_BOOT_DEVICE error message when I try to boot after changing "sata selection mode" from AHCI -> RAID in the BIOS.


      The supplier of my motherboard lists a dated version of the software (and the driver) on their website.

      I reckon this is fine because the newest package fails to install with "platform not supported" even though I picked windows 10 64 bit, in the download page.


      The older package from ASUS installs fine. I assume it installs the driver.



      If my board is supported by the newer package, then please tell me which one to download if not "windows 10, 64 bit" from this page (or fix your installer):

      Download Intel® Rapid Storage Technology (Intel® RST)


      I've tried the "setup rst exe" variant.

      I surmise someone forgot to translate a string, so the installer is crapping out on me for no good reason - please check the IntelRST.log.

      It could be that I need to enables RAID in bios for it to detect my "platform" as supported, but that is a chicken - egg problem in this particular case.

      i.e. I can  not boot if I enable RAID in BIOS.


      That was the background.

      The final objective:


      I want to stripe two drives in my system and access them from Gentoo (I am not asking for help with this process).

      There is a total of 4 drives in the system. Windows is not on a completely separate drive.

      Come to think of it, let us simplify the problem;

      Forget the other drives and the kind of RAID I want to set up and how I plan to use it.

      The problem:


      I need instructions on how to enable Windows 10 to boot from a non-raid drive while the motherboard SATA access is configured in RAID mode after the windows OS has been installed to a non-raid drive.





      I have also tried the "sysprep" method to allow windows to detect new hardware - but I did  not use the "generalize" option. Perhaps I need to do that?

      Anyway, I rolled back to a backup because It created a whole new user and messed up my quick-launch-bar and some other user settings.
