I am a little befuddled ... I have tried to install 16 Lite version 3 times and it does not honor the target selection ... it just gives a non ending error which requires shutting down the system. I use Ventoy for ISO loading BUT 16 Pro installs without issue but 16 Lite will not ...
I just tested this on a couple of older Machines...
Since another user posted the same complaint this morning (my time). Then you posted this new thread with the same trouble.
I had the same issue. Zorin OS 16 lite would only see and try to install on my External Hard drive. I had to unplug it - then it finally saw my primary drive.
Strange.
It seems there is something going on in Zorin 16 Lites Ubiquity installer.
