More problems when restoring computer after 1803 update. What now?

[carolfarrish]

I have been trying to get my computer up & running after a disastrous 1803 upgrade. I have put the suggested media file on a USB but it literally screeches when I put it in. Have tried this with 2 different usb drives. Suggestions?
