I created an windows installer on an USB stick with the windows media creation tool. Then I installed windows on my SSD. I skipped the steps which ask for a product key and selected the option 'I am reinstalling windows 10 on this pc. Now I have the error 'Windows reported that no product key was found on your device'. I already tried several things on this forum but nothing works.
Note that I can still boot windows on my other HDD, so I have installed windows 2 times on my laptop.
Does anybody have an idea what to do?
