Making an ISO image of a hard drive means creating a 1-to-1 backup copy that consists of a .iso file. Here are two ways to do just that.

To Dual Boot, say Windows and Ubuntu, on separate Hard Drives, you must first meet the prerequisite and then follow the steps mentioned here.

I was initially trying to make a multi-driver CD based on instructions from the previous admin, but it's assumed our spanking new server actually has a floppy drive (sorry, it doesn't).

I don't know what Fedora version you mean exactly, but up to Fedora 1, you could use "/sbin/mkbootdisk", as root, to create a booting floppy disk.
