Floppy image files (of whatever type) can be burned easily. .ima and .img files are examples of the uncompressed image files you'll need.
The article above gives you a Windows-ish idea of what to do, and to do it with Linux just select the .ima or .img file instead of reading a floppy.
Winimage will let you build floppy image files of various sizes without using a floppy drive. Play around, and build a few floppy emulation CDs (Windows, DOS, Linux) before you install LInux.
has a bootdisk.img file you can use for Fedora.
What is very cool is that they also supply a boot.iso file for you to burn to CD, (I'd try that first) and a rescuecd.iso too.
If using a second hard drive rather than splitting your current one is an option, it is the more reliable choice. If you aren't up to repairing Windows boot records yet, another drive (which can be small & inexpensive) in a swap rack or switched with a hard disk switch is isolated from your Linux experiments.
