Thanks to all who replied (or read my original post), the problem is resolved.
I followed the instructions in Thomas Schmitt's first reply, and things just worked. I need to try to puzzle out what I did differently the first time--I do know one difference, I was trying to make a logical instead of a primary partition, maybe that had something to do with it. And, I guess it is possible in all the attempts I made, maybe in some of them I hadn't umounted the drive before partioning (I'm about 95% sure I did, but ??. At this point in time, I probably won't file a bug against that document, but I'll think it over (sleep on it) and might suggest adding explicit instructions (like Thomas'). Also, I learned some other useful things, like lsblk. Thanks again! Randy Kramer On Thursday, August 18, 2016 03:45:06 PM Thomas Schmitt wrote: > Pascal Hambourg wrote: <good stuff elided>
