Windows Central Question
I bought HP Laptop may 2015 & then changed to W10 free upgrade end of July. Big mistake. After pressing power button, it said to press fn and esc. before activating & first thing to display was suggestion I insert ext media 64 GB flash drive to clone everything so that even if P/C died, so long as I had power I could insert ext media to return P/C to factory condition, so I did this. Then I activated P/C. Can I now use this to go back to W8.1, & should I format h/d or not before doing this. Can somebody please help me with this. I would be forever grateful. John L.
