I went back to factory specks using Windows 8 DVD which I made when I first got my computer. And as far as my Refresh & Reset are concerned I replaced the wiped out drive with a custom Refresh image and a complete system Image no problem there and something any user can do. See here; http://support.microsoft.com/kb/2748351/en-us . Hope this helps and if you need further assistance post and we will be glad to Help you.
