Yes, it’s installed.  When it’s missing, setup-storage terminates 
before creating any partitions.

Basically no part of this output makes any sense to me.  It’s 
activating a vg here:

    Executing: vgchange -a y vg1

But it either hasn’t (or isn’t logging) the creation of the VG.

Then it deactivates and removes the VG:

    Executing: vgchange -a n vg1
    Executing: vgremove vg1

Then tries to remove the PV.

Is it trying to tear down the existent (broken) disk structure 
instead of overwriting it?  Otherwise, I don’t understand what 
it’s trying to do by removing the PV containing the LVs it’s 
supposed to install onto.

I can give that a shot, but I’ll need some kind of EFI solution 
for this.

Sorry for the dumb question, but where would I add the "-d" flag? 
I’m creating a CD image and booting it on the target machine using 
Ventoy on a USB stick.
