Some updates. Restore didn't work. Next step was restore. Didn't work. Then restore from external device. I have a bunch of USB sticks that I create when starting a new machine. I had some order in them, such as size responding to storage on the device. So the ASUS having the least storage is on one of the smallest USB sticks, but Windows is so big that I have made new ones on a bunch of 8 GB sticks. Dumb move, I know. I should probably have put them in envelopes writing down the device name. Did get one to be recognized. It started, seemed to work fine and then I got a DOS message box saying "Secure Boot Violation" and then "Invalid signature detected. Check Secure Boot Policy in Setup" and then an Ok button. But touch isn't available so tapping it is useless, and I discovered that I no longer have a USB keyboard. All BT these days.
