NTLDR is missing

The NTLDR is missing error is a common error . This problem is not related with a typical problem. This  happens due to the missing  files. NTLDR (think NT Loader) is the first file that executes during the boot process it can be deleted and corrupted accidentally.

There are so many causes for this error (NTLDR is missing) like

• Corrupt NTLDR and/or NTDETECT.COM file.
• Due to improper shutdown the boot.ini file is corrupted.
• Hard disk drive is not properly setup in BIOS check the booting device priority that the hard disk is set or not.
• Computer is booting from a non-bootable source.
• Faulty or loose IDE / data bus / sata cable (connectivity media between hard disk and motherboard).
• Failing to enable USB keyboard support in the BIOS.
• Corrupt boot sector / master boot record.
• This problem  also occurs When new hard disk is connected to the motherboard  so format it properly and check connectivity media.

So, you can implement some steps to solve this problem. These steps  are:

1. Restore NTLDR from the Windows XP Setup CD via the Recovery Console.
2. At the command prompt, type cd .. and press ENTER.
3. Enter the letter of your CD-ROM drive like if your Drive having letter g type g: and then press enter it will show prompt g: .
4. Type cd i386 and press ENTER.
5. Type copy ntldr c: and press ENTER.
6. Type copy ntdetect.com c: and press ENTER (Ntdetect.com is another boot file that, when missing, can generate the NTLDR error.)
7. After this type exit in command prompt and then your computer will restart. 

copy command:
        copy F:\i386\NTLDR C:\
        copy F:\i386\NTDETECT.COM C:\ 


note: F is cd Drive letter
