BOOTLOG_LOADED
Boot log loaded-driver marker for BOOTLOG_LOADED
BOOTLOG_LOADED is bug check code 0x000000B5.
This value is a boot-log marker, not a conventional failure root cause. It is useful when shown as part of boot logging because it identifies a driver that successfully loaded before a later failure.
How to read it in a dump
- Use it as ordering evidence: what loaded before the crash or hang.
- A loaded marker does not prove the driver is healthy; it only says the load step completed.
- Pair it with BOOTLOG_NOT_LOADED entries to understand the boot set.
What to check
- Compare ntbtlog entries around the failure.
- Look at the next driver or service after the last loaded marker.
- Do not create a remediation plan from this marker alone.
