Actually, now that I understand a little more..you really dont even need to copy the installers on to the hard drive itself. Only the batch script files need to be on the hard drive to allow relevant directories (ie. %systemdrive%). So in this case, I would only have to copy the batch file to the hard drive..run it and then delete the batch file? What other advantages would I have by copying all the installers to the hard drive first rather than running them off the cd?
