    This fix worked perfectly for me the first try!

    Toobad said: View Post
    Hello everybody. What started out as a request for guidance ended up with me solving my own problem. Thought I may as well pass on my findings anyway just in case it helps somebody else in the same situation.

    So over the weekend, through a series of upgrades, I successfully hopped from Vista to Windows 10 Professional 64-bit. But, as is not unusual, I again managed to snatch defeat from the jaws of victory. With my new SSD loaded with Win 10 goodness, I realised I was still operating it in IDE mode. A confident dip into the BIOS to enable AHCI mode resulted in Windows then failing to start because it no longer recognised the boot drive! I'm guessing the AHCI driver wasn't loaded during installation since the mode wasn't in use. So back to IDE mode and a surf around for solutions. Plenty around pertaining to Vista, Win 7 and Win 8 involving changing registry values but nothing tangible for Win 10. However I found this alternative Win 8 workaround which I can confirm works equally well in Windows 10. I realise I'm probably teaching my Grandmother to suck eggs with this post here but perhaps somebody as equally technophobic as me, may find it useful. This is what I did:

    1. Run Command Prompt as Admin
    2. Invoke a Safe Mode boot with the command: bcdedit /set {current} safeboot minimal
    3. Restart the PC and enter your BIOS during bootup.
    4. Change from IDE to AHCI mode then Save & Exit.
    5. Windows 10 will launch in Safe Mode.
    6. Right click the Window icon and select to run the Command Prompt in Admin mode from among the various options.
    7. Cancel Safe Mode booting with the command: bcdedit /deletevalue {current} safeboot
    8. Restart your PC once more and this time it will boot up normally but with AHCI mode activated.

    Registered just to write this post. Thanks a bunch for this.

    I have a Dell Latitude E7440 running Windows 10 Enterprise on a 1 TB SSD 850 EVO
    I wasn't paying attention when I installed Windows 10 and the BIOS was set to RAID mode, even though I'm not doing any RAID. I'm going to install a Samsung 500 GB 840 EVO as a second drive to dual boot OSX Mavericks. OSX doesn't work in RAID mode, it wants to be in AHCI mode.

    Additionally my Win 10 partition is using BitLocker, so I was a bit hesitant that this would work.
    A few commands and reboots later and I'm running Win 10 in AHCI mode.

    Now on to dual-booting OSX and Win10!! Thanks again!

    I have the same computer with a 500gb 850 EVO. I'm new to this, why is ACHI better than RAID (controller currently configured to RAID in Device Mgr).

    Thanks,

    Rick

    Hello!
    Thanks for your post.
    However I tried this on my Dell XPS 13, but it did not work out as expected.
    I followed the steps and now I can start Windows 10, but it starts only every third restart.
    - First restart is black screen (with Dell logo)
    - The next restart is an error message: File: \EFI\Microsoft\Boot\BCD Info: The Boot Configuration Data is missing or contains errors.
    - The third time Windows decides to start
    Any ideas on this?

    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.

    RAID SATA default in my system, change to ACHI for new SSD Boot drive?


    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!
