Boot Status File

Labels:

Windows uses a boot status file (%SystemRoot%\Bootstat.dat) to record the fact that it has progressed through various stages of the system life cycle, including boot and shutdown. This allows the Boot Manager, Windows loader, and the Startup Repair tool to detect abnormal shutdown or a failure to shut down cleanly and offer the user recovery and diagnostic boot options, like Last Known Good and Safe Mode. This binary file contains information through which the system reports the success of the following phases of the system life cycle:

• Boot (the definition of a successful boot is the same as the one used for determining Last Known Good status, which was described earlier)

• Shutdown

• Resume from hibernate or suspend

The boot status file also indicates whether a problem was last detected and the recovery options shown, indicating that the user has been made aware of the problem and taken action. Runtime Library APIs (Rtl) in Ntdll.dll contain the private interfaces that Windows uses to read from and write to the file. Like the BCD, it cannot be edited by users.
