    These steps can be used in windows 10 to go back and forth from raid mode to achi, or achi to raid, mode depending upon what you need...



    • If currently installed, uninstall your RAID or AHCI SATA driver (for intel, intel rapid storage technology)
    • Basically open msconfig -> boot tab -> check safe boot -> restart
    • Go into UEFI/BIOS and set SATA mode to which ever one you want
    • Boot up into windows safe mode
    • Open msconfig again -> under the main menu tab (general) click the normal startup circle - > restart
    • Your system should boot into windows fine and you can install your AHCI or RAID driver.

    Just got a new Dell XPS 8900. My default SATA in the BIOS is RAID. So my existing SATA internal 1 TB HDD is configured with this RAID setting through Windows System 10, correct? I want to prepare for and soon format a SATA SSD, (Samsung 850 PRO 512GB 2.5-Inch SATA III Internal SSD) which I understand requires ACHI, correct? If I change my BIOS now to ACHI, will my system still see my original installed HDD 1 TB Toshiba drive? Later I have a Samsung 950 Pro PCIe SSD coming to install which I want to make the start up disk by cloning my original installed Win 10 HDD. Should I just wait and do that with the Samsung migration software to clone my original Win 10 HDD to the 950 Pro SSD (PCIe)? OR do I need to change the whole system first to AHCI to accommodate future SATA SSDs? I hope I can clone my system and files to a startup SSD. I already have a lot of apps and files and local users installed. Sorry for the newbie question... Thank you...

    Hey, I registered just to say THANK YOU. In my case, I was in AHCI mode and wanted to switch to RAID mode to set up an array with a couple storage drives. There was no problem with the RAID setup, but of course Windows on my SSD wouldn't boot with the bios in RAID mode. Your idea did the trick, and now I don't have to reinstall windows.

    So seriously - thanks Toobad. I owe you one!

    YOU ROCK! I just upgraded a Dell AIO that had a small SSD caching for a 2GB HDD. I installed a 2GB Samsung850 EVO in place of the original HDD. Restarted, all good, but realized that the controller was still set for RAID. Your suggestion on how to change to ACHI worked perfectly and saved me a ton of time. THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Hello Woodbridge. I have a similar setup with my Dell laptop. I upgraded from win 8.1 to win 10, then cloned the HDD to a Samsung 850 EVO SSD. I replaced the HDD with the SSD and it booted fine. Entered BIOS and saw SATA was set to Intel IRST. Changing to AHCI resulted in boot failure. I have tried to disable/delete the 32 GB cache m-sata SSD in Device Manager and in Computer Management\Disk Management, but it re-appears when I reboot. I think Windows keeps reinstalling it on reboot and then assumes I want a RAID setup. Is that what's causing Windows to reject the AHCI setting? Any thoughts on how to eliminate the m-sata cache drive so Windows only sees one SSD?

    This worked. Nothing else had... Running an AMD based mobo (Asus M5A88-M w/FX-8350: I couldn't get my new SSD to run in AHCI mode in Win7/64, no matter what technique I used. In-place upgrade to Win10 and your instructions made it work.

    Many, many thanks, your suggestion worked perfectly when I couldn't get AHCI to switch from IDE after installing a Samsung SSD. You're a lifesaver!
