I don't know what happened to my previous reply, I never got a copy (It was witten on my tablet because I was working in the house). Here is an approx copy. I send separately to you a photo of the output of ls -lah /dev/disk/by-id` My apologies to you & the list but I could think of no other way. I can find no reason to believe I was writing to the usb & I was aware of the risk of doing that when I tried to write grub to sda1 Mant thanks for your help.
