Why each option
When a Windows OS fails to load at startup, enabling boot logging helps diagnose the problem by recording which drivers and services load or fail. This log provides critical information for troubleshooting startup issues.
Enabling boot logging (usually through Safe Mode options or system configuration utilities) creates a ntbtlog.txt file that lists all drivers and services loaded or not loaded during startup. This log is invaluable for identifying the specific point of failure when the OS has trouble loading.
The 'Last Known-Good Configuration' option was available in older Windows versions (up to Windows 7) but is not present in Windows 10/11.
Task Manager cannot be accessed if the OS is failing to load at startup, as it requires the OS to be running.
sfc /scannow is used to check and repair corrupted system files once the OS is running, but it's not a primary diagnostic tool for initial OS loading failures where the system doesn't even boot.
The Event Viewer application log requires the operating system to be running and fully accessible; it cannot be used if the OS fails to load at startup.
