Hello, I just did a new win10 1803 install 64 bit on a machine. I found something i've never seen before and am wondering considering I am now unable to duplicate the action. I've got the secure boot in my uefi set to disabled and I created a thumb drive using win10 media creation utility. This went fine. At first the system would just go in to windows without booting off the thumb drive, I tried several USB ports, one would boot off the thumb drive then on a subsequent boot not do so then another would, now none will. Ok, so I assumed on the times it wasn't booting off the thumb drive that it wasn't working. Somehow and this is what i'd like to do again, I got to what is presumably the recovery screen, it has things like continue (boot hard drive), repair advanced options and usb uefi drive boot. How I know this is I hit narrator's keys thinking it had booted off the thumb drive and narrator actually read out this recovery screen. I'd like to get back to this screen. Has anyone else seen this behavior? Thanks. Dave.
