I have a Lenovo Idea-pad flex10 running on win 8.1 64 bit. I have had it for a month now, but it isn't new (2016). I had the machine working just right, and made a restore usb drive, from following the advice I was seeing on my screen. I have made 3 of these usb restore drives in total as backups. Whilst making one of these backups, the actual system backup partition was wiped (not deliberately by myself).
I have unsuccessfully tried to restore the computer with each of these discs by using all of the methods I can fathom from the settings menu.
as a last resort I have been able to do a reset of the computer, but I am now required to enter a product key, which is not on the machine , the box ,or power supply.
Is there anything I can do to make it work again?
