The aliases are those values in
the output that are enclosed in curly braces that are not GUIDs??”that is, {ntldr},
{current}, {bootmgr}, and so on. As an additional shortcut, if you simply run
BCDEdit.exe without any switches, it defaults to running the following:
BCDEdit.exe /enum ACTIVE
Table 1-7. Four Ways to Manipulate the BCD
Method Description
System Control
Panel applet
Very limited ability: lets you set the default OS, the time to
display the list of OSs, and the time to display the recover
options when needed.
MSConfig.exe This GUI allows control of startup options. Select the Boot
tab from the five-tab interface. The General, Services, and
Startup tabs control additional startup options. Most common
boot settings can be set, enabled, or disabled using this tool,
including debug settings and safe mode options.
BCDEdit.exe This command-line tool is one of the most powerful tools
for BCD manipulation. It??™s recommended for systems
administrators when modifying the BCD due to its flexibility
and ease of use. It exposes most of the boot settings and
supports scripting.
WMI If you are into scripting and need more than even BCDEdit.exe
provides, you can manipulate BCD straight through WMI. This
offers the greatest flexibility since you can use any scripting/
programming language that can use WMI to make the changes.
This is significantly more involved than BCDEdit.
