Part 1 What are NTLDR files?

Also used an abbreviation of the NT loader, these files happen to be the boot loader for all the releases of the Windows NT Operating System. This is extended up till Windows XP and Windows Server 2003. While the primary hard drive is used to run it, portable storage devices that include a CD-ROM, Flash Drives, Floppy Disk, are also used in order to run it. Alongside, NTLDR offers the capacity to load non-NT-based OS if the appropriate boot sector in a file is present.

This is not all, as NTLDR, at least, requires the following files to be on the system volume for a smooth function.

1) NTLDR, which happens to be the main boot loader file itself.

2) NTDETECT.Com, as it is essential for booting an NT-based Operating System. It can detect the required hardware information that can help in a successful boot operation.

Alongside, the boot.ini file is also required as this contains the boot configuration.

The NTLDR file is launched by the volume boot record of the system partition and it is written to the disk through the functions of Windows FORMAT or SYS command.
