Why do I encounter if the NTLDR is missing an error?

You will run into the NTLDR missing error due to several underlying reasons. Some of the prominent ones are:

• PC boots from a non-bootable source – Misconfigured BIOS boot sequence can cause the computer to boot from a non-bootable source like a floppy disk or flash drive.
• Incorrect active partition in the bootable volume – If the active partition of the bootable disk is incorrect, your system will terminate the booting process and will display the error code.
• Wrong boot sector code is installed – If the older NTLDR-compatible master boot code is applied during manual boot loader configuration instead of the newer BOOTMGR, the error is likely to occur.
• Corrupt or missing boot-related files – The missing NTLDR error can also show up if the boot-related files such as NTLDR, and NTDETECT.COM get corrupt due to a power outage or virus attack.
• Too many files in the root folder – The presence of a large number of files in the root folder causes the Master File table to get fragmented such that a new allocation index has to be created.
