I want to run recovery on my HP 14 AC016ne machine. However, I had updated my system to Windows 10 when I got it. The recovery partition is still there but C was resized. The recovery partition has 20 GB space and it contains the files. I am not sure how to run it to restore it to its original state of Windows 8 that came with it as I had upgraded it to my own Windows 10 pro that I had purchased separately from elsewhere.
