The links you show mention Windows 10, not Windows 7. It is not reasonable to call a "fix" a complete reinstallation of Windows. If the system partition is necessary, then the Windows installer has a bug as it allows installing Windows 7 in a single partition.
Sounds like an IT manager we once had, she would reformat everyone's computer the second she counldn't resolve a simple issue. Most of us had to keep her away from our PCs with a baseball bat !
