Open your burner software and it should give you the option to create an image Cd,
take this option and burn away!!
I got this of the redhat Linux site it should help you make the bootable floppy once
you've made your CD,assuming your using MS Windows.
Making a Diskette Under MS-DOS
To make a diskette under MS-DOS, use the rawrite utility included on the Red Hat Linux CD in the dosutils directory. First, label a blank, formatted 3.5-inch diskette appropriately (eg. Boot Diskette,'' Supplemental Diskette,'' etc). Insert it into the diskette drive. Then, use the following commands (assuming your CD is drive d:):
C:> d:
D:> cd dosutils
D:dosutils> rawrite
Enter disk image source file name: ..imagesoot.img
Enter target diskette drive: a:
Please insert a formatted diskette into drive A: and
press --ENTER-- : [Enter]
D:dosutils>
rawrite first asks you for the filename of a diskette image; enter the directory and name of the image you wish to write (for example, ..imagesoot.img). Then rawrite asks for a diskette drive to write the image to; enter a:. Finally, rawrite asks for confirmation that a formatted diskette is in the drive you've selected. After pressing [Enter] to confirm, rawrite copies the image file onto the diskette. If you need to make another diskette, label another diskette, and run rawrite again, specifying the appropriate image file.
