Isnert system disk

Check to make sure you don't have a floppy disc in the drive.

No there is no floppy disk in the drive,it booted up OK before but now it just says insert system disk ,which I don't have, I cannot get boot up from hard drive with setup, which was how I did it previously, only floppy and cd rom but these won't boot up

I'm afraid to say then that this normally indicates that the hard drive has failed.

OK thank you very much for your help
