Certification Training: A+ Windows Boot Process
The Windows Boot Process occurs in the following order:
The NT loader is used to load the Windows NT kernal. This relies on both boot.ini and ntdetect.com. The NT loader is located in %systemroot%.
The boot.ini is a configuration file used by NTLDR to load the operating system. The boot.ini file is located in %systemroom%.
The ntdetect.com detects and loads various hardware devices and it uses the hardware keys found in the registry.
The ntbootdd.sys is an alternate loader file used when the main disk is SCSI-based instead of IDE. The ntbootdd.sys is not handled by the BIOS firmware.
