Enable Boot Logging
This starts Windows normally, except that a log of every step is
recorded into the ntbtlog.txt file, located in your \Windows folder. If
Windows won??™t start, all you need to do is attempt to start Windows
with the Enable Boot Logging option at least once. Then, reboot your
PC, press F8 again, and choose one of the Safe Mode tools above (preferably,
Safe Mode with Networking). When you??™re back in Windows,

read the log with Notepad; the last entry in the log is most likely the
cause of the problem.
Enable low-resolution video (640 ?— 480)
This starts Windows normally, but in VGA mode (640 ?— 480 resolution
at 16 colors). This helps you troubleshoot bad video drivers or incorrect
video settings by allowing you to boot Windows with the most compatible
(and ugliest) display mode there is.
Last Known Good Configuration (advanced)
This starts Windows with the last set of drivers and Registry settings
known to work. Use this if a recent Registry change or hardware installation
has caused a problem that prevents Windows from starting. See
???Go Back in Time with Restore Points and Shadow Copies,??? later in this
chapter, for details.
Directory Services Restore Mode
Don??™t bother with this unless the PC is a Windows NT domain controller.
Debugging Mode
This option, typically of no use to end-users, sends debug information
to your serial port to be recorded by another computer.
