The upshot is all my partitions except one has gone, including the entire OS partition. The one partition remaining has now expanded to the size of the HD. I have tried to save it using TestDisk, to no avail, so now Im trying to save my missing files using PhotoRec.
My problem is, I cant work out how to save the found files to my external HD. (as now the remaining partition is the entire HD, I cant save back to there).
I did read on this forum something about not being able to save to a NTFS and needing a different type of boot disc?
Could someone please explain, using very small words, how I save my files to my external HD?

Thank you.
