Ok, thanks for your tips. I know the tip of the ribbons so thats not the problem.....I'm using or try to use a ME startup disk and a W98 startup disk, none of the 2 works get the same error each time i tried. So i think the problem is what iowaboy said: "more than likely you will have to replace the floppy drive".
So i desactivate again the floppy adn hope it burn in hell
I aint gonna buy a new floppy i better make the starup disk in a cd or a zip , anyway thatnks for the help and tips
