What is the full form of NTLDR?
The full form of NTLDR is NT Loader. It is a boot loader, basically found in every computer that runs the Windows NT operating system, which includes Windows XP. NTLDR is usually run from a hard disk drive but it can be run through a portable hard drive (Pen-drive, CD, Floppy, etc.) when NTLDR is missing in your computer.
Minimum two files are required to run NTLDR in your computer which is given below –
- ntldr – Its a main boot loader file
- NTDETECT.COM – It support for booting an NT-based operating system, main function is to find out basic hardware information.
- boot.ini – This file includes boot configuration menu, which allow user to choose which operating system to boot.
How do NTLDR works?
Windows NT was launched for Advanced RISC Computing (ARC) based platforms, which depended only on its boot manager support and provided the only osloader.exe.
Windows directory partitioning, a loading program accepting normal command-line arguments, is launched by the ARC-based boot manager when a user starts a specific Windows NT operating system. Whenever x86 lacked any ARC support an additional layer was added specifically to that platform.
Custom boot manager code, it allows the user to choose from one or more operating systems, and its options are in the boot.ini configuration file, which is created by using special startup modules that allow starting CPU in safe mode, such as responsible for the tasks.
In all operating systems Windows Vista and Windows Server 2008 onwards, NTLDR was spit into its own boot manager (Windows boot manager) and system loader (windows.exe).
Future of NTLDR
In recent times, the use of NTLDR has been greatly reduced compared to the era of Windows XP. In Windows 10, Windows 8, Windows 7, and Windows XP, BOOTMGR is used, not NTLDR.
This shows that the importance of NTLDR has been revoked out in the computers. Earlier, whenever the NTLDR was missed, the computer would not turn on. But now at the time of installation OS, if NTLDR is missing, then try restarting the clean install process from scratch to solves this issue.
