creating a boot disk for ghostcast 8.0 on usb key?

Hi

I’m trying to make a network boot disk on a usb stick as apposed to a cd or using floppy disks, simply copying files from floppy disks to usb, does not work…. has anyone found a way around this?

have tried using hp software to make usb stick bootable,

any ideas though would be greatly appreciated!!!
