Thanks for the info.
I'm getting the gist about the defrag allowing me to effect the maneuver.
Always best to start with a clean slate.
Not 'arf, but I was never asked if I wanted to format...and believe me, I was watching for that like a hawk.
SoCal implies that the question re format comes first.
That has to be the answer, cos the only thing I can think is that I accepted the saving of Windows.old, which then precluded a format. (the OS wouldn't have been wise enough to think to use other logical drives.)
Shame that...I would do the whole thing again if it wasn't for pushing me luck with MS.
I'll think about reinstalling, while I try to fix the sound issue. I'll start a separate thread on that so this stays on one track.
