Repairing a corrupt Windows installation is always a difficult task for beginners especially when you are not able to boot into Windows. Even though one can always use the Windows 7 installation media to boot into Windows Recovery Environment (WinRE) to fix startup problems, it’s also possible to repair Windows 7 boot issues without any installation media.
Unlike previous versions of Windows, Windows 7 automatically installs the Startup Repair tool onto the operating system partition, so that the user can access diagnostic tools without the help of installation media.
By default, after an unsuccessful boot, Windows 7 automatically loads up the startup repair tool and tries to rectify the problem, if possible. If you can’t see Windows 7 automatically loading startup repair after the unsuccessful boot, you can manually run the startup repair tool without the installation media.
