I installed Fedora Core 3 via ftp on a second drive configured as a slave. It would be accessed in a multiboot environment using a boot manager like GAG. So I didn't install a boot loader thinking that GAG would handle this.
But when GAG identifies the Fedora / partition on this drive and I attempt to boot from it, I get an error stating: "Boot sector not found or invalid."
So my question is, without reinstalling, can I go back and install a boot loader on the / partition of the Fedora install on the second disk?
Yes, you can. Boot in rescue mode and run grub-install on your Fedora root partition from there. See Terry Polzin's post in the "Re: GRUB will not be overwritten" thread twenty minutes ago.
