Modifying the Operating System Boot
You can the set default operating system using the System Configuration
utility or the command-line Boot Configuration Editor, bcdedit.exe. Follow these
steps to use the System Configuration utility:
1. Open the Start screen, type msconig , and hit Enter.
2. Click the Boot tab.
3. Select the operating system from the list you want to make the default
and then click the Set As Default button.
4. When you are finished, click OK.
Using the System Configuration utility is the easiest way to set the default
operating system, but you can also set it with the bcdedit.exe utility. Follow the
next steps to use the Boot Configuration Editor to set the default operating system:
1. Open the Start screen, and type Command Prompt .
2. Right-click on the Command Prompt shortcut at the top right.
3. Select Run As Administrator from the charm application bar on the
bottom of the screen.
4. When the command prompt has loaded, you are ready to use the bcdedit
.exe command. First, you need to get the ID of the operating system that
you want to set as the default. To do this, type bcdedit /enum all in the
open Command Prompt window. Scroll through the list of entries and
look for Windows 8.
5. After you have found the correct entry, note its identifier. You use this in
the next step.
6. At the command prompt, type bcdedit /default (entry identifier) . For
example, I ran bcdedit /default {b2721d73-1db4-4c62-bf78-c548a880142d}.
The default operating system on the Windows Boot Manager is now set. The
next time you reboot, your changes will be applied.
TIP The Boot Configuration Editor is a powerful utility that you can also use to
change many other settings of the Windows Boot Manager. Experiment with
bcdedit.exe by running bcdedit /? from the command prompt. This shows
you all the other available options and lags that you can use with the Boot
Configuration Editor.
