If the computer prompts you with a "no boot sector" error at startup, it usually means that you are starting your computer in traditional BIOS mode. Are you sure that Windows on your computer was installed in traditional BIOS mode instead of UEFI mode? Windows installed in UEFI mode uses the GPT partition scheme, and when we start Windows from a GPT disk in traditional BIOS mode, the computer usually prompts the "no boot sector" error.
