Helping a friend that has a HP Laptop that he upgraded from Windows 7 to Windows 10. When you start the computer a message comes up saying Diagnosing Windows 10. After a "long" time a screen comes up offering you to Troubleshoot, reset the computer, or continue to Windows 10.
Have tried everything. There were two System Restore Points. Neither work. Tries and then fails.
Tried doing a system refresh and it fails. Same with System Reset. It starts but then fails too.
Is there anything else that can be done. I am thinking it might be better to install Windows 7 again (I have the disk and keycode) and then upgrade to 10.
It is a big job and one I don't want to do but I don't see a way out of it. Any ideas would be most appreciated.
Thanks so much.
