NTLDR is missing press any key to restart in Windows XP or windows 2000

While I booting the windows machine, I received the following error message.

"NTLDR is missing press any key to restart."

Solution:

1. Turn on the affected Win2000 computer, insert the Win2000 CD, and reboot the computer from the CD.

2. When you see the Welcome To Setup screen, press R to repair a Win2000 installation and then press C to start the Recovery Console.

3. When prompted, select the appropriate installation and then type the Administrator password.

4. At the Recovery Console prompt, type the following commands, where X is the drive letter assigned to the CD-ROM drive, pressing ENTER after each one:

COPY X:\i386\ntldr c:\
COPY X:\i386\ntdetect.com c:\

Keep in mind that if you are prompted to overwrite an existing file, you should do so.

5. At the Recovery Console prompt, type c:\boot.ini and press ENTER. If the file is found and you see a listing, skip to step 8.

6. If the Boot.ini file is missing, you can recreate it by typing the following:

CD \
COPY CON boot.ini
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect

Keep in mind that the string that appears under the [operating systems] header is all one long line.

7. When you finish typing, press CTRL-Z, press ENTER, and then save and close the file.

8. Remove the Win2000 CD and type exit to quit the Recovery Console and to reboot the computer.
