Microsoft has completely reengineered the boot environment for Microsoft Windows Vista to address the increasing complexity and diversity of modern hardware and firmware. One aspect of this reengineering is a new firmware-independent data store that contains configuration data that influences the boot process. This paper provides an overview of this configuration data - called boot configuration data (BCD) - and describes how to use the related tools to manage boot options.

What's New:

  • References to Longhorn removed
