Windows Help and How-To: Startup Repair: frequently asked questions
Startup Repair is designed to detect operating system startup problems
and troubleshoot any found and correct them with little user
interaction. It can repair problems such as:
- missing or corrupt drivers
- missing or corrupt system files
- missing or corrupt boot configuration settings
- corrupt registry settings
- corrupt disk metadata (master boot record, partition table, or boot
sector.)
When the Startup Repair Tool has taken control, it analyzes startup log
files for clues about the source of the problem and launches diagnostic
tests to determine the cause. If it determines the cause of the failure,
it attempts to fix the problem automatically. After successfully
repairing the problem, it will reboot the system, and notify the user of
the repairs, filing a detailed report in the Windows Vista event log.
If the Startup Repair Tool can identify the cause of the problem, but
can't repair the problem by itself, it will provide access to a set of
tools that you can use to manually troubleshoot the problem further.
One of these is the Bootrec tool described below.
If the Startup Repair Tool cannot identify or repair the problem, it
will roll back the system to the last configuration that was known to
work (Last Known Good Configuration.) Again it will add detailed
information about the problem to the Windows Vista event log.
