Because the boot sequence runs the hard drive first.To Change this when the computer boots up shift into setup. You probably either press F1 or Delete.When setup open you can go through the setings and find boot sequence,and devolution it so that the floppy is read first.
Maybe your bios is not set to boot to floppy drive. Check your computer bios.
