How do you know when the Installation is finished?
The following image is the last Screenshot I was able to take and that was over 90 minutes ago. !!
I saw it reach over 40% and then the System Install window was closed. I’ve just opened the Task Manager and I see that cl-update-checker is active but I have no idea if that is responsible for the delay in finalisation of the installation.
System should be correctly installed, no matter what you choose, if the installer did not display the error messages. You can remove the USB Drive after reboot.
