This error message usually appears in cases where the system loader has lost access to the shared boot files "Ntldr" and "Ntdetect.com" In this case, the computer simply cannot start its normal operating system boot.

Experts identify the following reasons:

  3. Ntldr and Ntdetect.com boot files themselves can be deleted as a result of user actions or software failures.
  4. The error appears as a result of changing the active partition.
  5. Computer hardware errors - hard drive malfunction, outdated BIOS, connected external or hard drive with another operating system.
