Creating ProDos Bootdisk for Apple IIGS

I just recently got a iigs and am trying to remember how to create a prodos boot disk. I have a prodos bootdisk ver prodos 16 1.3 . It boots fine up into gui interface fine. But what I am trying to do is just create a prodos bootdisk that will boot to just basic or the command line. I can launch sysutil.system and format a blank prodos disk but it does not copy any of the files to boot the disk. I found on the web that I need to copy prodos.sys and basic.system onto the newly formatted floppy in order for it to boot, but after doing that and rebooting to that disk i get an error that says no system directory found? Am I doing something wrong?
