sytem disk failure

I switched off my machine(dell gn+) with a win98 operating system revoved a floppy drive and when i switched it on it gave an invalid system disk error. I then tried to boot from a floppy(win98 boot disk) and when i changed the drive to c: it would do , but any command i would type thereafter would not do (like dir).Used a magic bullet disk and got no viruses, tried norton recovery disk and got invalid media reading drive c:, when i slave the HDD I can see it in windows , but can not access it.If I run norton recovery disk from within another disk i cxan see the folders on my HDD but can not restore them. Please assist
