I Need a boot floppy

Hello,
 I am a newcomer to Ububtu Linux. I do not know how to make a boot floppy, Please help(novice level).
 My system has Ubuntu Breezy installed in the default partions of

hdb, this is a 40 GB disk so there is no problim with room.

I have installed on hda Windows XP SP2 with a disaster recovery system called Acronis True Image V8.0. this program works verry well and I Do Not wish to uninstall it for obvious reasons.
 When Acronis installs it over wrote the MBR so that you can recover your system before Windows starts. It ouverwrote the GRUB boot manager, hence the need for a boot floppy.

 Any assistance would be greatly apreciated.

thanks,
Charles Shaffer
