Install from HD with graphic Yast2??

Hi, Is there any possible for me to install suse from Harddisk with the interface of graphical Yast2, just like the one on SuSE CD installation?? Or, where can I get it (linuxrc from cdrom boot)? Is it legistimate for people to hand out the linuxrc from the cost version of suse? For people who download suse from ftp are capabled to make their own version of suse installation ISO with graphical Yast2 installation possible. Thanks for answering / helping. jsc
