Making a boot CD

I have a set of 2 diskettes - one of them is bootable.

I would like to make a boot cd from these 2 diskettes.

I tried Roxio Easy Media cretor-- but it allows only 1 diskette to be used.

I tried to copy ALL the files from these diskettes to Cd, but hen it is not bootable.

I made images (using Roxio) as ISO, and copied them to Cd, but still not bootable

My questions are
1) Is anyway to make a bootable cd from 2 diskettes (NOT multiple boot)
2) is there a way to combine 2 images into 1
