    Windows 10 Preparing Automatic Repair, Fails, boots on second try.


    This is a Dell Precision M7510. Has a Samsung 950 NVME 512GB SSD in the M.2 slot as the main OS drive. A secondary 512GB SSD is installed in the SATA slot as a DATA drive. This system has Windows 10 Pro on it, installed from an imaging software at our work. Countless other systems have this same WIndows 10 image without issue. Two other 7510s have the same setup (M.2 boot drive) without issue.

    I power on this system and after about 10 seconds I get the "preparing automatic repair". Then Diagnosing PC, Attempting repairs, then "Couldn't repair" Shutdown or Advanced Options. If I shut the computer down, turn it immediately back on it boots just fine. Here is a copy of the srttrail.txt file.. Any ideas?

    Hi, suggest you check your disk.

    Then consider

    Chkdsk is fine:

    Yes, but chkdsk won't check the area you need to check. Try Crystal Diskinfo and Macrorit DiskScanner

    Good to know that! Try Startup repair with a Win 10 disk, then if that doesn't work, the MBR repair.

    A Macrium Reflect boot disk also offers a repair sequence - you can try that.
    v5: How to fix Windows boot problems (Restore, Windows PE)

    If that fails there's at least one more possible step.

    Will do. I actually have the pro version of Macrium

    Other disk checker said all clear:

    I ran the repair from Macrium. Went from original error to "We need to check your disk". I did some more reading of the error logs and discovered that it wasn't cleanly shutting down. Some more reading, and I turned off the Windows 10 Fast Startup. Haven't had a startup issue since. I noticed the NVME driver for my Samsung SSD was 1.4.7.17, and there's a newer version (2.1.0.1611). Installed it tonight and may turn the windows 10 fast startup back on to see if the issue returns..

    Fast startup has had some adverse consequences for some users, mostly related to drivers. You have a SSD so don't need it anyway...

    Glad you've found a solution.
