As far as I know the livecd cannot work without the cd. You can try using unetbootin to make a live-usb while you're in the livecd. You would need syslinux and unetbootin which you can get here:
http://download.opensuse.org/reposit...44.12.i586.rpm
and here:
http://download.opensuse.org/reposit...6-1.3.i586.rpm
So install syslinux first then unetbootin. Download the .iso and then use unetbootin to put the iso on the usb stick.
Unetbootin will be installed to /usr/sbin/unetbootin
so you can open a terminal and type that in to use it.
You can then boot and install from the usb stick.
Take Care,
