Trouble installing 7.10

[Bruce Bales]

Hi, Guys,

I downloaded the iso for Kubuntu Gutsy 7.10 to update my Dapper 6.06 
systems and burned the CD using k3b.  Spent an hour trying to get 
that working0 and then downloaded another iso from another mirror and 
got the same result.

Time to read the README; it talks about SMB, a smart loader for floppy 
disks.  I cursed a while then went to another machine that has a 
floppy drive, booted into Dapper and did a 

sudo dd if=SMB.bin of=/mnt/floppy/SMB.bin 

Machine says it's a non-system disk.

How do I make the floppy into a system disk?
