Windows utilizes four boot files, and you will need an understanding of all four of them for the A+ Exam. The four boot files for Windows are:
- bootmgr: Operating system loader code; similar to ntldr in previous versions of Windows.
- Boot Configuration Database (BCD): Builds the operating system selection menu and data resides in the BCD store. You can edit the boot configuration data with the bcdedit utility.
- exe: Loads the Windows operating system if selected from the operating system selection menu provided by BCD.
- exe: Resumes the Windows operating system if the system is started from a hibernate state.
