Thought I would have a go at this when I heard about the opportunity on Windows Weekly, knowing I could learn something under way.
If all went well I would have learnt nothing, but it didn't. I made the flash drive, but I just couldn't get it to work. After a lot of time spent looking for the answer, I wrote a post on the relevant Windows forum, and went on to try another PC, my old T91MT.
This installed with none of the Samsung's problems, and, though the screen resolution is lower than the prerequisites, everything else worked much faster than Windows 7..
This success led me back to the Samsung, where a couple of lucky Google searches pointed me at the Rufus flash drive builder. First efforts with this failed to install as well, but another lucky search led me to producing another Rufus build, this time in FAT32 format. Lord knows why, but that allowed me to complete a custom install, which got rid of all the Samsung rubbish, which was so difficult to remove in 8.1.
From there it was all plain sailing :-)
Once I was happy with the status, I carried out a new Macrium Backup, very fast now! I also looked into Recovery, making Bootable flash drives for both PCs, and custom Recovery folders with the help of reagentc and recimage. (See Evernote)
This used up all the old flash drives, so I ordered a couple of new ones, which might arrive today.
