  • The first main reason why this error happens in detail: The NTLDR file is a critical component of the Windows 7 installation process. It contains the necessary instructions for loading and starting the operating system. If the NTLDR file is missing or corrupted, the system will not be able to boot.

Using a bootable USB drive with a different operating system

  1. Step 1: Create a bootable USB drive using a different operating system, such as Windows XP or Windows 8. This can help you access the recovery environment and potentially repair or reinstall Windows 7.
