Over the weekend, I attempted to reconfigure some of the drives in my Hyper-V server at home.  Note that I said “attempted”.  I ran into hardware issues and ended up having to revert back to my old configuration - but somehow in all of this – I broke my system disk. Specifically it would not boot any more. This did not phase me because I knew that the excellent startup repair tool in Windows would soon have me up and running – which it did.
