How to Enable Boot Logging in Windows
from Troubleshooting Your PC For Dummies, 3rd
Two event log
that come in handy for troubleshooting your PC are the boot log
These files are created when you specify boot logging as a start-up
option. The files are
named either ntbtlog.txt or bootlog.txt, depending on how old your PC is. These files,
found in the Windows folder, list the success or failure
of various pieces of Windows as it's loaded into memory
from the PC's
mass storage system.
You can enable
or disable boot logging by using the MSCONFIG utility
. Follow these steps in Windows
7 and Windows Vista
Press Win+R to summon the Run dialog box.
Type msconfig and press Enter.
In Windows Vista, type the administrator's password or click
the Continue button.
Click the Boot tab.
Place a check mark by the item Boot Log.
Click the Restart button to restart now. Otherwise, click
Exit without Restart.
The logging doesn't take effect until you restart Windows, and you
have no reason to do so immediately unless you really want to see the
Windows XP, you
can enable boot logging by pressing the F8 key when Windows first starts and
choose the item Enable Boot Logging.
The boot log is overwritten every time you start Windows. And,
the log is produced only when you turn on the boot logging option.
What can you do
with the boot log? You can check for the failed installation of certain pieces
of Windows or device drivers
. The drivers or files are obviously flagged in the log.
Because you know the filename, you can then either disable it from loading or
look for an update.
Activating the boot log in Windows 7 or Windows Vista means
that you configured your PC for a custom start-up. If that bothers you, disable
the boot log after you cull whatever useful information you need from the boot
log file; repeat the steps used to enable boot logging, but in Step 5, remove
the check mark.
Traditionally, computer logs are all text files. They may
have the filename extension log, or they may use txt instead.
You can search for log files by using the Windows Search command.
Simply look for files named *log* anywhere on the hard
drive, including system, hidden, and non-indexed locations.
Most log files are in plain text, but the text may be organized by
using the XML, or Extensible Markup Language. XML is merely a way to
organize information, and although XML files are readable as text, to get the
most from the information, you should use an XML reader, such as the Event
If you find the file boot.ini on
your Windows XP computer, you can enable boot logging by modifying the file.
Open it in Notepad and look for the line that contains this text:
(That's only a portion of the line; in the
file, it's longer). Add the text /bootlog to the end of
the line. Save the file. When you restart Windows, boot logging takes place
