(well, technically, i'm not sure that's completely true, is it? i've had others tell me that you need to reboot to recognize any new *extended* partitions, but not new *primary* partitions. is there a definitive answer to this?) so, yes, while you have to reboot, you do *not*, as the guide says, have to get into rescue mode. that's a little bit of overkill, methinks. rday
