Hello everyone I recently was resetting my windows 10 lenovo laptop and while it was reinstalling windows and all the drivers for it, it said that windows cannot be installed please click OK to restart and continue installing I tried this a few times but it did not work and I need this laptop working because I am selling it to get a new one I am not too sure what to do here but is it possible to install windows 10 again using an ISO image? And if so do I need a product key because I don't have a windows 10 product key my laptop came with windows 10 installed and I never found out the product key thanks in advance for help!
