BOOTLOG_ENABLED
Boot logging enabled marker
BOOTLOG_ENABLED is bug check code 0x000000B7. This value is diagnostic context. It means the boot path is recording driver-load progress, which can be used to correlate a later crash or hang with driver-load ordering.
How to read it in a dump
- Do not treat the marker as a failing driver.
- It is useful for reconstructing boot order and comparing multiple boot modes.
- Combine it with loaded and not-loaded entries.
What to check
- Preserve the boot log before retrying many times.
- Compare the last successful and failed boot logs.
- Use it together with dump analysis rather than as a replacement for a crash dump.
