I started it creating a new partition last night so I could reformat my old one (Windows is giving me fits). I went this morning to look at it -- "Non-system disk, please replace..."
<sigh> I was tired and didn't want to wait for it, but I guess there was nothing too entirely critical on there. Any chance that if I install PM5 on my other computer and create the rescue disks that I can revive my partition (only one main one on the other system, I was creating a smaller secondary one)? Fatigue made me careless.
