    Switch from Raid to AHCI


    Is there a way to switch from Raid to AHCI without losing everything and having to reinstall Windows again?

    :)

    Windows 10 dual boot, 64bit installed, but 32 bit won't.

    Well, that was easy.

    RAID was activated in the BIOS. Switched to AHCI, and everything seems to be doing fine.

    Iam Stuck in safe mode loop on Windows 10

    Michel,

    I am glad it is all sorted out.

    I am still surprised that Asus supplies computers set up in RAID. I have two with SSDs and they have both always been set to AHCI.

    I did not know that you could just switch straight from RAID to AHCI with no untoward side-effects.

    All the best,

    Denis

  4. Switch from Raid to AHCI

    1. Run MSCONFIG
    2. Enable Safe Boot (minimal)
    3. Reboot into UEFI/BIOS and change to AHCI
    4. Boot up into safe mode
    5. Run MSCONFIG and disable Safe Boot.
    6. Reboot

    And do be sure you have a copy elsewhere of anything you don't want to lose, that exists nowhere else. Any time working with drives one risks possibility of something failing at the worst time.

    Switch from Raid to AHCI

    Is there any advantage to switching to AHCI?

  9. I'm assuming you're talking about Intel RST when referring to RAID. In theory, if you don't enable any RAID features then there should be no difference - Intel RST sits on top of AHCI so if you don't have RAID configured then all drive commands should just pass through the RST layer to the AHCI driver.

    Indirectly, there may be some marginal performance difference depending on whether you use the RST or AHCI driver - Forum - Performance of the Intel RST/RSTe AHCI/RAID Drivers

    Another thing I can think of is that boot may be slightly faster in AHCI mode since the UEFI won't have to load the RAID driver. But I haven't verified if this is noticeable.

    Thanks PolarNettles, That worked perfect. The only thing that I had to do was assign my DVD drive a new drive letter. I had it as X:.
    I think it starts faster and is a little more snappy now. Thanks Berton for your input. I'm marking this as solved.
