    windows 10 professional version 1607 build 14393.969 64 bit

    For this sequence is the drive letter the same for each command line so that all c become all d?


    • c:
    • bcdedit /export C:\BCD_Backup
    • cd boot
    • attrib bcd -s -h -r
    • ren c:\boot\bcd bcd.old
    • bootrec /RebuildBcd

    and what happens if there is no cd boot in the command sequence?

    Any references to learn the commands along with simulated sequences for different problems is appreciated.

    I have made a mistake with drive letter BCD store is located at C: partition so there is no need to change below commands.


    • c:
    • bcdedit /export C:\BCD_Backup
    • cd boot
    • attrib bcd -s -h -r
    • ren c:\boot\bcd bcd.old
    • bootrec /RebuildBcd

    Hi, @BobbyG reported
    1.
    I can always get back in with a system restore
    = PC boots again
    2.
    I found this in the SrtTrail.txt log file. Boot critical file C:\WINDOWS\System32\drivers\ACPI.sys is corrupt.
    3. ACPI.sys is a driver, and thus protected by System Restore.

    Therefore, it is possible something is corrupting this (obscure) once the PC is booted.

    That is why I suggested the sequence in Post #5, which is not difficult to try.
    @BobbyG- could you do that and report the result if you've not tried it?

    On another track, please
    a. Run Startup Repair - you'll need to boot from a Win 10 installation disk.
    (Presumably you're starting system restore having booted from Win 10 installation disk so you have one.)
    b. Post a screenshot of your partitions using Minitool Partition Wizard
    - expand all columns as necessary so all text is visible.
    To post a screenshot please use the Insert Image icon above your post to the left of the video icon. Thanks.
