Welcome to the Microsoft upgrade world David! I have done several Win 10 upgrades which took from about an hour to maybe 3 hours. Something went wrong in your upgrade. I too have had that happen. Trying it again would usually fix the problem. Unfortunately, I don’t have any fix for you to try. If it hit the 99% complete, perhaps it may boot to Win 10 if you shut it down and restart. It can then repair any needed items. I did this on one system. Perhaps others on the list may have other suggestions. Good luck.

I had to abort the first atempt after about 12 hours, apparently with no harm done. My second attempt has been showing "99% complete" for about 72 hours so far. How much longer should I wait for it to complete?
