I need to upgrade Windows 8.1 to Windows 10 on a laptop. The problem is that I want to repartition my hard drive. Currently I have two partitions and I want to combine them. If I just update to win10, it will stay as it is, with all the files.
I can also install it from windows image from bootable usb and reformat my hard drive there. Although I don't know which license code to use for installation then. I tried entering the code from System Info in Windows 10 fresh installation, but it rejected it
Can I look up the licence code in the system info and use it to reinstall Windows 8.1 fresh and then upgrade? Or what's the optimal solution?
