Two suggestions: first on the USB stick with the Windows 10 ISO, plug the USB drive into another running machine, go to disk management and check that the file system on the USB is FAT32 and that the drive is marked as active (bootable). If all that is good, go into the BIOS on the bad machine, and in the boot menu, disable secure boot and enable legacy boot. Then try again with both the USB and your DVD(s).
USB Windows 10 ISO is FAT32 and active. DVD is UDF Healthy (Primary Partition). I built the PC with an ASUS motherboard and the BIOS doesn't those options in the boot menu. I did change the USB from Auto to Enable in another menu. I even burned another DVD by another program with no different result. What puzzles me is that occasionally a starting window "Preparing Automatic Repair) appears and it goes to a screen of different countries with "US" highlighted. The keyboard does not react when I hit "enter" or any other key. The keyboard works otherwise. I even dug out my old cabled keyboard and plugged it in. It works but not on the repair screen. At the bottom of the screen is "See More Keyboard Layouts".
Back to the drawing board! Thanks for hanging with me TriX.
