thank you.
I ran PerfectDisk and it seemed VERY effective. I was able to shrink the WIndows 7 partition to about 30% of the total (so about 72Gb)
On retrying the Ubuntu Install Ubuntu still does not "detect" my WIndows 7. But on trying SomethingElse I see what looks like an unused 172GB "Free Space" area.
Can I "direct" ubuntu to install there and thereby leave the WIndows 7 Intact and unaffected? or do I have to do some other steps first? (I was tempted to say To Heck WIth it and just use WIndows, but on doing the Live Install of Ubuntu I am reminded of how much I like it.)
In any event, here are the results of those commands you suggested (I hope this is clear and helps)
