When I log into my computer I am greeted with a black screen and the error message above. After looking up how to fix the error I realized that people can navigate their computer which I cant all I can do is go into recovery state and into bios as well sometimes when I log in my Wallpaper Engine is open. I've tried resetting my computer fully but it messes up very early in the process.

    Hi Christopher, This is Ramesh.

    1. Please take a photo of the error message window and share the image here.
    2. If you can load the recovery options, open WinRE Command Prompt and run SFC offline. Follow these steps:

    In WinRE Command Prompt, please run:

    bcdedit | find "osdevice"

    Note the OS drive letter in the output. Suppose it's C:. Then run:

    sfc /scannow /offbootdir=c:\  /offwindir=c:\windows  /offlogfile=c:\sfcoffline.txt






notepad c:\sfcoffline.txt

    Post the contents of c:\sfcoffline.txt.

    If SFC doesn't run (as sfc.dll is corrupt), please post the output of this command:

    (If C: is the OS drive as per BCDEDIT output).

    Run:

    dir c:\windows\WinSxS\sfc.dll /s /a
