HOW TO FIX NTLDR Is Missing Error In A Computer

There are a number of possible causes for NTLDR errors, including the most common “NTLDR is missing” issue.

The most common reason for this error is when your computer is trying to BOOT from a hard drive or flash drive that is not properly configured to be booted from. In other words, it’s trying to boot from a non-bootable source. This also would apply to media on an optical drive or floppy drive that you’re trying to boot from.

Other possible causes include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE Cables.

Solution 1. Restart Computer

Restart your computer. The NTLDR missing error could be a fluke.

Solution 2. Unplug All Removable Media

Since the “NTLDR is missing” issue is often caused by BIOS trying to load from an external non-bootable drive, you can try unplugging all external drives, and remove all removable media, such as CD, floppy disks, memory cards, and USB devices to make sure the BIOS doesn’t try to load from any of them.

Solution 3. Change BIOS Boot Order

Alternatively, you can check the BIOS boot order to ensure that the PC tries to load from an internal drive first. To check the boot order, follow these steps:Note: Make sure that the device you will select has boot files (or Windows operating system files) installed.

Step 2: Press the necessary key to open BIOS menu. This key depends on the computer manufacturer and computer model.

Step 3: If the screen shows multiple keys, please find the key to open “BIOS,” “setup” or “BIOS menu.”
