Hello,
I downloaded the nbrt.iso and wrote it to a USB stick following the YouTube instructions with Rufus (see picture).
When I try to boot the USB stick with the F12 key, nothing happens. The USB stick is not recognized as a boot stick at all. I have tried it with two different sticks on two computers. Other boot USB sticks are recognized without any problems and also boot. The error is therefore due to the current nbrt.iso.
My request to the Norton people concerned: please recreate the nbrt.iso.
