For a harddisk the code in the Master Boot Record first sector determines the active partition. The code in the boot sector of the active partition could then be again a NTLDR boot sector looking for ntldr in the root directory of this active partition. In a more convoluted scenario the active partition can contain a Vista boot sector for the newer Vista boot manager with an ntldr entry pointing to another partition with a NTLDR boot sector. When booting, the loader portion of NTLDR does the following in order Accesses the file system on the boot drive either FAT or New Technology File System, NTFS.

VGA mode by using a video device driver that is compatible with any video adapter. If the operating system fails to load due to a faulty or incorrectly configured video driver, this switch allows the system to load, so the user may then remove, update, or roll back the video driver causing the problem. Using this switch in conjunction with the SOS switch helps to determine the driver that is triggering a failure. BAUDRATEnnn Sets the baud rate of the debug port that is used for kernel debugging.
