    Switch from Raid to AHCI


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

    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.

    Is there any advantage to switching to AHCI?

    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.
