Thanks for the help. It was quite an experience reloading my Win 10 to a drive that had a pirated Win 10 Pro. A catch was the flash drive version would only load to a GPT drive so I was forced to use CMD and sort that out. Now I have all genuine programs on the confuser again and I am impressed with how much Win 10 has developed in the year I did not use it. A problem now is my 2 TB USB drive is not recognised but is visible in Admin tools. It has 1.4 TB of backup date on it. I will use EASUS Partition Manager to convert this to GPT. Not keen as I have two two other backup USB drives and one standard drive as backup using a dock. All these use MBR. I am not keen to do this change but not seeing a way round it.
