location of Log when using Boot-Rescue-Media?

Hi!
When I use the Boot-Rescue-Media to e.g. clone a drive from one harddisk to another and chose NOT to shutdown when the task is finished I can easily see what happened when I look in the left panes "Log" section.
But most times I'd like to have the computer shut down after it has finished - which is an option when you start the actual clone-process (where you can chose to restart or shutdown the computer when the action is completed)

But if I select "Shutdown after finished" - how would I know if everything worked?
How to access the "Log" then?

Hope someone can help!

Thanks a lot in advance!

Bye, Rudi
