If your drive is detected during POST but doesn't appear as a system disk, then either the boot sector on the hard drive is corrupted or the system boot files are missing or corrupted. You'll find a reasonably good guide to troubleshooting the situation at:

You'll need a Windows 98 Boot diskette so you can boot from your floppy drive, and if you haven't got a woring one there then make one on a friends Windows 98 system, get your local computer shop to make one for you if they're friendly enough, or download the necessary boot diskette image from:
