F9 system repair will display the same message.
The owner did not have the Windows 7 installation CD, so I torrented an iso with a start up repair only and put it into a bootable USB. The first time I booted from the usb it worked okay, I just selected start up repair and it orders me to restart. The computer will still not boot and whenever I try to boot the usb again it gives me the Windows boot manager telling me that Windows failed to start.
Info: the Windows boot configuration data file does not contain a valid os entry
Any help greatly appreciated.
