Answer 1

Don't you mean NTLDR?

That is your windows boot loader. If you made a rescue disk you can boot from that disk and then copy that file back to the root of C:\

Here are instructions on how to make a boot loader disk.

More than likely since your NTLDR is corrupt you will have to have to restore your system using the system restore disk.

Answer 2

Here is how to fix this problem below.

1. Boot to a command prompt by using a boot disk (if you have one. Otherwise you can make one from any Windows 95/98/ME PC.

2. At the command prompt, type fdisk, and then press enter.

3. Click set active partition, choose the partition that you want to make active, and then hit enter.

4. Press Esc.

5. Remove the boot floppy disk, restart the computer.

Using the Recovery Console, copy the Ntldr file from the Windows XP CD-ROM to the root directory of the current active partition. Follow these steps:

1. Start your computer by using the Windows XP Setup floppy disks or by using the Windows XP CD-ROM.

2. At the "Welcome to Setup" screen, press F10, or press R to repair.

3. Press C to start the Recovery Console.

4. Copy the Ntldr file from the Windows XP CD-ROM to the root of your system partition by using the following commands, pressing ENTER after each command:

1. Type cd .. to go to the root of drive C. (Note the space)

2. Type the letter of the CD-ROM drive

3. Type cd i386 to change into the right directory

4. Type Copy ntldr c:

5. Type Exit

If the partition was not formatted by using Windows, you might also need to run the Recovery Console fixboot command to make the active partition bootable.

After you can boot into Windows, it is recommended that you use the Windows Disk Management snap-in tool to reset the original system partition as the active partition, and then restart the computer.

From Microsoft:

If the NTLDR is missing or damaged try the Recovery Console.

To start the computer and use the Recovery Console to replace the boot sector

"Insert the Windows XP Professional Setup CD-ROM into the CD-ROM drive.

Restart the computer. If prompted to press a key to start the computer from the CD-ROM, press the appropriate key.

When the text-based part of Setup begins, follow the prompts. Press the R key to repair a Windows XP Professional installation.

If you are repairing a system that has more than one operating system installed, from the Recovery Console choose the Windows XP Professional installation that you need to repair.

Note

If you press ENTER without typing a number, the Recovery Console quits and restarts the computer.

The Recovery Console might also show valid installations of Windows NT 4.0. However, the results of attempting to access a Windows NT 4.0 installation can be unpredictable.

When prompted, type the Administrator password. If you do not have the correct password, or if the security database for the installation of Windows XP Professional that you are attempting to access is corrupted, Recovery Console does not allow access to the local disks and you cannot replace the boot sector.

To replace the boot sector, at the Recovery Console command prompt, type: fixboot [drive:]

If you do not specify a drive letter, the Recovery Console replaces the boot sector of the system volume. If you need to replace the boot sector of a volume that is not the system volume, then you must specify the appropriate drive letter."

Answer 3

It's possible your computer's hard disk drive may have a corrupt boot sector and/or master boot record.

Try to repair this using the Microsoft Windows Recovery console by running the fixboot and fixmbr commands.

Boot from the Windows 2000 CD, and run the above command (fixboot)

Answer 4

Surely you mean NTDLR? Most of the time, this means your OS is hosed. You're probably going to have to reformat and reinstall windows.

Wow.. you got a real answer from me. Lucky.

Worked great for me 3X in different PCs and one of our peers here.

Format is a last resort and for the desperate only.
