If you are running a dual-boot setup with more than one Windows operating system, It’s pretty easy to configure the default boot operating system with the GUI interface.
Note that if you are using Windows 7 or Vista as one of the operating systems, you will need to make this change from 7/Vista, not XP.
First, you’ll need to right choose Computer and select Properties:
Next, click Advanced System controls
Now choose the controls button under Startup and Recovery
And just snag the operating system you want to use:
Easy stuff.
You could also use the bcdedit command to do the same thing from the command line, but it’s probably easier this way.
