Just asked and got a solution to a question about a blue screen and not being able to start my computer in normal or safe mode (solved by using Kaspersky rescue disk). In the process I had changed boot order so I could boot from USB. After the cure for the blue screen I changed boot order back to what is was before which is Hard disk, optical disk, USB. But now, each time I reboot I get a message "Floppy disc(s) fail (40)" and I have to press F1 to continue to the hard disk boot-up. So far as I know I changed nothing else in correcting the blue screen problem. The F1 thing is not a big problem but is annoying. Any solution that works will be appreciated.I searched the knowledge base for a solution but found none that seemed appropriate for my situation and computer.
