When I use the free win10 upgrade on my laptop from win8.1 to windows10, the updates are downloaded (about 3GB) and then the machine restarts, after which it takes me to a "choose an option" screen, which I have never seen before. However the main option is "Continue: Exit and continue to Windows 8.1"
Well, I thought I was installing 10.
I selected the 8.1 option, went back to updates, and it started to download everything all over again!
How do I actually proceed with the upgrade?
