Easy questions get easy answers! Just right click the floppy drive and choose format. Then there is a check box to make the floppy bootable. it says under format options:
Make Floppy Disk Ms-Dos Bootable.
As for making a CD bootable you need to copy system files to that disk. Some cd burning programs have that as an advanced option. But you could use the old AskTheAdmin.com workaround and copy the bootable floppy files to the cd (Make sure you show all system and hidden files!)
