My computer says it is missing and will not continue to boot.

First make sure you don't have a floppy disk in the drive (if you have a
floppy drive). If you do, remove the disk and the computer will boot.

If you don't have a floppy in the drive (or no floppy drive):

Boot with your XP cd and take the "R" for "Repair". This will get you
into the Recovery Console. Assuming your cd drive is D: (substitute the
correct letter if it is not):

COPY D:\i386\ntldr C:\ [enter]
COPY D:\i386\ntdetect.com C:\ [enter]
(a file that may also be missing)
then rebuild the boot configuration boot.ini file by
Attrib -H -R -S C:\boot.ini [enter]
(if not found skip the next line)
DEL C:\boot.ini [enter]
BootCfg /Rebuild [enter]

Why did you post a new thread half a hour after the old one?

We answered you over there.

It's a simple program that loads the OS.

It is a hidden file on the boot partition. I don't know if only Windows
uses NTLDR or if it is a generic bootstrap loader, but it gets created
when Windows is installed in a partition.

This is probably connected to where you formatted your hard disk in the last
post you made. NTLDR is a file on the disk that would have been one of the
many you erased when you formatted the disk.

Perhaps you might get better help if you back up a bit, start at the
beginning and explain what it is you are trying to achieve?

Hello,

I have just started studying on Windows. As per my consideration NTLDR is a bootloader. When you install OS on your hard drive, boot information is placed into boot sector of your HD and at the same time NTLDR is placed into boot sector of HD.

Boot process involves following steps :

1. POST (Power On Self Test){It will check power supply to all H/W connections}
2. BIOS (Basic Input Output System){It will check necessary H/W devices with it's priority like FD, CD, HD}
3. MBR (Master Boot Record)

Where MBR contains sequence as NTLDR >> Boot.ini >> BootSect.dos >> NTDetect.com >> Ntoskernal.exe

In short NTLDR is communicator program between h/w system and OS.

Please correct me if I am wrong.

Thank you.

About query that only windows have NTLDR or not. It seems each OS have it's own boot loader like in LINUX you will find GRUB as a Boot Loader. In case you have installed 2 OS on your machine like WinXP and Linux then GRUB boot loader will be taken into consideration 1st and depends on option you have selected like WinXP or Linux it will start with booting. If you select WinXP then it will load the NTLDR and if you select Linux then GRUB will continue it's work with boot loading process.

Please correct me I am wrong.

Thank you,
Abhi

Your homework is wrong. The 446-byte bootstrap area of the MBR doesn't
care which operating system is installed. NTLDR is in partition in
which you installed the Windows operating system.

You'll need to do more homework.
