I started again, creating install disk on Linx 8, and tried to install via Linx 8 but got error messages.
Then I went to my Laptop for part 2, and used that to install, and it worked worked ok.
I tried to boot into disk via my laptop, and was surprised - it worked quite well to a point.
Only hurdle I came up against was when I installed a test app, the screen rotated, with the app on its side (on a phone/tablet, you would have the phone held in portrait mode). Also, mouse actions were sideways too (correct for portrait mode), making it hard to navigate (my pc does not have touch screen).
So I was positivised (yes its a real word I just discovered) by this, and then tried it on my Linx 8. It recognised the boot drive, booted from it, got to the selection menu, and I clicked on the top line (not debug line). Screen went blank and drive flashed away looking as if it was working, then eventually nothing.
So something (technical term) is not working on Linx 8.
Will try debug mode and see if that gives a clue.
