This sounds like a Drive Image error. Vfloppy (virtual floppy) is what it uses when it reboots from Windows to create an image of your drive. Once the image process is successful, the "fake" floppy is removed. So, it sounds to me as if an activity has not been satisfied. Do you have Drive Image installed or can you add more to what sequence of events led up to this?
When I boot up my computer I get the error message err5;vfloppy.sys and err8;cannot find fake floppy drive
