What are NTDETECT.COM Error Messages?

NTDETECT.COM Runtime Errors

Runtime errors are EaseUS Disk Copy errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these COM errors are triggered when NTDETECT.COM is attempted to be loaded either when EaseUS Disk Copy is starting up, or in some cases already running. Runtime errors are the most common form of COM error you will encounter using EaseUS Disk Copy.

In most cases, NTDETECT.COM runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these NTDETECT.COM error messages mean that EaseUS Disk Copy was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, EaseUS Disk Copy will be unable to start without resolving these errors.

Finding the source of the NTDETECT.COM error is key to properly resolving these errors. Although most of these COM errors affecting NTDETECT.COM will happen during startup, occasionally you will encounter a runtime error while using EaseUS Disk Copy 3. This can occur due to poor programming on behalf of EaseUS, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of NTDETECT.COM errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
