So once upon time many OS's ago, the mfg of these fine machines would supply an installation disk and if you had problems, you could re-install from that disk. Now, you have to go through a few steps to re-install the OS, it would appear. When I had tech support on the line recovering my pocket drive for general use, she also downloaded something called, Rufus which I have not installed. I am going to download Macrium to this Dell - since I would like everything recovered - guess that's the best thing for me to do. Thanks again for your help.
