Hello when may I remove the USB stick from my PC because I want to put my laptop over the Media CreationTool completely new and then I can just format it and then use it again normally?
When the installation is complete
Yes you can.
So if I'm on the normal desktop then right?
When the message comes that the installation is complete, you can take it out.
OK thanks
As soon as the message comes that you should restart the PC
As a rule, Windows should have copied all the necessary data from the USB stick to the hard disk after the first message "Restart computer". For security, you can leave it in but also until the normal desktop comes for the first time.
After Windows has been installed, you can of course format the USB stick and use it elsewhere
