How do i make a bootloader run on bochs without having to burn it on a cd?

Bochs allows you to create files on your disk, within your current OS, and "pretend" that the files are hard disks, or floppy disks. Then the problem becomes one of just writing the correct data to the files.
You can also use an actual floppy drive.
It is also possible under a *NIX OS to attach a hard drive to your system, and use the entire hard drive for your new OS, under bochs.

mkisofs?

Try using dd (*NIX) or partcopy (Windows).
