What Causes The NTLDR to be Missing Error?
You may see the NTLDR is missing an error due to various reasons. Anything that disrupts the booting process of your computer can be considered a potential cause. Let’s take a closer look at the most common causes of this error.
Corrupted/Damaged System Partition: One possible cause is a corrupted or damaged system partition. This can happen if your computer experiences improper shutdowns, disk errors, or gets infected by malware. When the system partition is affected, it triggers the NTLDR missing error.
Any Issue with the boot.ini File: The boot.ini file holds essential information about the operating system and the boot process. If this file becomes corrupted, deleted, or misconfigured, your computer won’t be able to locate the necessary instructions to start the boot sequence. As a result, the NTLDR is missing an error message appears.
Failed Hardware Components: Hardware failures, like a malfunctioning hard drive or faulty IDE cables, can also lead to this error. When critical system files cannot be accessed due to hardware issues, your computer displays the error message.
Misconfigured/Faulty Boot Sector: The boot sector, a small section on the hard drive, is responsible for initiating the boot process. If the boot sector is misconfigured or becomes faulty, it can prevent your computer from finding the necessary files, resulting in the NTLDR missing an error message.
Incompatible or Outdated BIOS: If your computer’s BIOS (Basic Input/Output System) is outdated or misconfigured, it can cause compatibility issues with the operating system leading to the error message.
Incorrect Boot Order: The boot order determines the sequence in which your computer searches for bootable devices. If the boot order is incorrectly set in the BIOS, your computer may attempt to boot from an improper source, resulting in the error.
Booting from Removable Media: Sometimes, leaving a non-bootable floppy disk, CD/DVD, or USB flash drive connected to your computer can cause the NTLDR to be a missing error. The system might try to boot from these devices instead of the designated boot drive.
