    Failed AHCI change from RAID on Dell 5500, w10p 1909,


    Followed this tutorial - Enable AHCI in Windows 8 and Windows 10 after Installation Printed it and did it carefully step-by-step. Found each and every bit in registry. Reason is to get a Linux distro to see the WinOS and others(penguins) have found that many Dell laptops are not set to AHCI. Previous bios settings were RAID (never changed by me) - this was the third of 3 options - Disabled, AHCI, RAID. After following steps in tutorial made the change from RAID to AHCI in Bios (made no other changes). Machine failed to restart into Windows, repeated boot loops (as far as I could tell) and the Dell SupportAssist muscled in twice trying to get a download of a complete image - cancelled by me). Eventually Windows presented a blue recovery box with "Restart" or "Advanced options". Tried both .. only ever choosing restart within advanced though. Repeated fails. Went back to BIOS and reverted to RAID = success and back into w10p. All I want to achieve is for Linux to "see" Windows folders/files just like the old days with w7p .... ahhh, those were the days. Machine = Dell 2019 version Latitude 5500, i5 8th gen, 16GB ram, 256 nvme ssd with w10p 1909 build (up-to-date), storage microSD in slot (no boot or OS on it), nothing else connected/plugged in. EDIT: Checked regedit for those values and found these... ...Services\iaStorV = start still set to '0' value data ...Services\iaStorAVC\StartOverride = Value Name is '1' not '0' and value data is '3' ...Services\storahci = Start still set to '0' value data ...Services\storahci\StartOverride = Value Name is '1' not '0' and value data is '3' Paul

    Try this method:
    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
