Known good bootable on BIOS only systems too, or would you have always UEFI booted this stick before? > Ubuntu, Fedora the system fails to post. Fails to post as in doesn't get past the POST? Any beeps? If it's really failing during or before POST that would rule out anything software related, from boot loader on down. > 1. Dell logo comes up > 2.

This would contradict it being a POST or pre-POST failure unless it was by chance. I dunno, I've had an old laptop whose keyboard would fail unpredictably in ways that seemed to be related to total power draw. It wouldn't get far trying to run Windows 2000, but OpenBSD or Slackware with a lightweight wm would run for hours at a time with all or almost all the keys working. I supposed that some component or circuit had gotten where voltages were in some ambiguous area that was somehow a function of current or else heat was changing physical distances between parts in tricky little ways that started to matter over time. Maybe your friend's machine has some kind of power budget issue that it's getting crankier about over time, and one of your USB sticks draws current a bit differently than the other. -- Mike Small sma...@sdf.org _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
