In that installation CD you have files to make boot floopies (need 6 I think), but since your floppy isn't being recognized you can create a boot CD through Nero (if you run Nero). I never did, but maybe you can copy all your installation files on to the working computer then use a software that can copy those files while making that CD a bootable one. Again, I only am familiar with Nero.

If you could somehow get to DOS prompt, try copying the NTLDR file from your working computer's root directory to the installed computer's root.
