I'm not sure about the mean of this step, is it to change the text 
printed at early boot time (a kind of menu?) ?
Anyway, make sure you don't have an error here.

When you look inside the usb key, is everything alright?
I mean do you have all files and folder in root directory?
Because I may have issued a slightly modified command line i.e.:

genisoimage -o debian-7.8.0-i386-CD-1-mod.iso -r -J -no-emul-boot -boot-
load-size 4 -boot-info-table -b isolinux/isolinux.bin -c 
isolinux/boot.cat ./debian-7.8.0-i386-CD-1-mod/*

And last, I just had a weird idea (or not?) , you could try to load your 
system in a virtual machine (virtualbox, vmware ...) so you could follow 
step by step the boot process (from the outside I would say!).
