What is NTLDR?
NTLDR is short for NT loader - a program loaded from the hard drive boot sector that displays the Microsoft Windows NT startup menu and helps Microsoft Windows NT load। So when it goes missing for some reason, your windows cannot load। I use Windows XP on a Pentium 4 PC.
“When your computer starts, the BIOS attempts to find the primary hard drive’s active partition to read the first sector for the MBR (Master Boot Record), it uses that info to load the rest of the OS। For Windows NT4/2k/XP the NTLDR (New Technology Loader) takes it from there। If you get the “NTLDR is missing, press any key to restart” what’s most likely going on is the BIOS either didn’t look for the right drive, didn’t find the right partition, it wasn’t active, didn’t find the MBR, or the MBR didn’t list NTLDR in the right place, or the location of NTLDR changed।”
Cause:
1. Computer is booting from a non-bootable source.
2. Computer hard disk drive is not properly setup in BIOS.
3. Corrupt NTLDR and/or NTDETECT.COM file.
4. Misconfiguration with the boot.ini file.
5. Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32.
6. New hard disk drive being added.
7. Corrupt boot sector / master boot record.
8. Seriously corrupted version of Windows 2000 or Windows XP.
9। Loose or Faulty IDE/EIDE hard disk drive cable.
