SOLUTION: Switch Windows 10 from RAID/IDE to AHCI operation

It’s not uncommon to find a system on which RAID drivers have been installed and something like the Intel Rapid Storage Technology package is handling storage devices, but where an SSD might require AHCI operation for more optimal performance or configurability. In these cases, there is in fact a way to switch operation from either IDE or RAID to AHCI within Windows 10 without having to reinstall.  Here’s how.

  1. Right-click the Windows Start Menu. Choose Command Prompt (Admin).
  2. Type this command and press ENTER: bcdedit /set {current} safeboot minimal
  3. Restart the computer and enter BIOS Setup (the key to press varies between systems).
  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
  8. Reboot once more and Windows will automatically start with AHCI drivers enabled.

That’s all there is to it!  Special thanks to Toobad here for outlining this procedure.

  1. Blue screen and endless repairing disk cycles for me 🙁 (single disk to no actual raid was ever on, but maybe some interaction with the SSHD being to used to accelerate perf?). 🙁

  2. Thank you so much for these clear and simple instructions. I had no idea it was this easy to avoid having to reinstall Windows!

  3. Wow thanks! I thought disabling SRT in windows then in bios switching to ahci was enough but nope. This did it. Thanks

  4. I used msconfig to boot into and out of safe mode, therefore not needing to edit the registry. Was able to change from RAID to AHCI, thanks!

  5. does not work for me.. it says:

    PS C:\WINDOWS\system32> bcdedit /set {current} safeboot minimal
    The set command specified is not valid.
    Run “bcdedit /?” for command line assistance.
    The parameter is incorrect.

  6. I had the same error as Mark (“The set command specified is not valid.”), I’m running a brand new Windows 10 machine.

    I got it to work by removing “{current}” from the command:
    > bcdedit /set safeboot minimal
    > bcdedit /deletevalue safeboot

    And your solution worked great, thank you!

  7. When I switch from Raid to ACHI then save and exit it just says “Missing Operating System”. I successfully switched it to safe mode before this, is there anything I can do?

  8. Tried this fix just now to find that now instead of just freezing, my pc now just decides to turn itself off. The setting was already on AHCI. And on top of that my keyboard isn’t working either. Nice.

  9. So the setting was already AHCI? Obviously this would suggest nothing was changed then. Have to tell you this, but it sounds like you’ve got deeper issues at play. You need to get ahold of a local technician you trust to help you out.
