The machine needs repair so you can boot from said devices. I'd re-evaluate that you've backed up what you can't loose and determine what you want to do about this failure.
You all gave me fine advise BUT, My big problem is when I bring up safe mode, normal etc. whichever one I punch it goes to the black screen with a blinking cursor that just keeps blinking. It wont recognise my floppy or the cd rom so I can't even format and start over.
