NTLDR is missing on LG XD4 External Hard Disk

[VivRichards]

I was having Dell Dimension 4600 laptop with windows vista home premium operating system installed on it. I was also having Avast antivirus installed on my laptop so that my system could be protected from malware, adware etc. I have plugged an LG XD4 external hard disk into the laptop. When I tried to boot from the external hard disk, the booting was failed. The booting was failed displaying an “NTLDR is missing” error message. I tried to start booting again but failed. I need a solution so that I can fix this error message and the booting could startup.

NTLDR is the boot loader files for windows platform. NTLDR can runs on primary hard disk drive as well as on external devices such as CD-ROM, USB drive, floppy drive etc. NTLDR is responsible for loading the system files. If the NTLDR file is missing or corrupted then your system may fail to boot. If the NTLDR is missing then you can fix it by making use of Windows operating system CD and if NTLDR is corrupted then you can make use of the system recovery option to repair it. When you have fixed the NTLDR problem, your system may start booting without any problem.
