The the computer does not recognize the hdd at all, you should boot into the bios and make sure the computer finds the hdd. If it's there and continues to give you this error, then your hdd has crashed. Replace it.

If you recently made some disk drive changes, it is possible that the primary partition is not set to active.

Boot with a boot floppy,
run fdisk, and check the drive properties.
Make sure that the primary partition on the boot drive is set as the active partition.

The other answers are true but your cmos battery could be bad or a virus could have over written the boot sector. A simple answer do you have a floppy in the drive? Try replacing the battery and set the hard drive in the cmos to auto to see if it sees it. Use a antivirus boot disk to see if there is a virus. If your hard drive is not seen look at the drive and write down the c/h/s and manualy enter them in the cmos. To see if boots to the drive. A controller could have gone bad, try removing the cdrom cable and attaching it to the hard drive. And reboot.

First thing is that u chk whether there is no floppy in the floppy drive.
Second chk in the bios whether the HDD is being detected by the BIOS.
Lastly, if every thg. above is fine then insert the 98 bootable floppy and transfer the system files tour harddrive

Install an OS???? Nah seriously make sure your bios is booting from the right harddrive, and that the IDE cable hasn't come out.
