Figure 3. The relationship between boot.ini and BCD
Note: Figure 3 uses descriptive labels for BCD objects and elements. In practice, they are represented by names that depend on the particular tool. Some commonly used names are given later.
There are three general categories of BCD objects: application objects, inheritable objects, and device objects. The most common type of BCD object is an application object, which describes a boot environment application such as the Windows boot manager or Windows boot loader. Each object is represented by a 128-bit unique GUID and contains a 32-bit description that describes the type of object.
The following table shows the object codes and associated object code values for the three object categories.

Figure 4 shows the layout of the type. The details of how data is packed into bits 0 through 27 depends on the category.
