Sorry, lost your thread for a while.
It was staring me in the face. Disk 0 only has 15 GB free.
I still want to understand the setup before then next step
Boot to the install media again
Shift+F10 to open Command
sel dis 0
sel dis 1
Take another picture of the diskpart output
and post it as you did before
Press the X to exit the install if that's where you return after closing the Command Prompt
Thanks, hopefully that will give me what I need to make a decision.
