I had the same problem as you.
I downloaded a boot cd with a few bootable tools to work on the hard drive.
My recommendation is to do the following:
Download Ultimate boot cd.
Burn the ISO
Burn the correct one. (The one with all the tools)
Use your manufacturers programs on it to work on your hard drive.
pop in your Fedora Core 3 cd. in text only mode.
give it a try.
and USE http://www.google.com/linux
