Ciao,
I'm Ugo, a Microsoft Independent Advisor willing to help other Microsoft customers.
Regarding your question, it looks like recent OS upgrades are causing issues, sometimese severe. So please try the below:
- PERFORM A SYSTEM RESTORE OR A STARTUP REPAIR
a) Power on and off your computer three times. On the third time, your computer will boot into WinRE
OR
b) In Windows 10, select Start > Settings > Update & recovery > Recovery > under Advanced Startup, click Restart now.
OR
c) Boot to recovery media.
OR
d) You can configure a hardware recovery button (or button combination) to run a secondary boot path that includes WinRE. - https://msdn.microsoft.com/en-us/ie/dn898475(v=vs.94)
THEN
Follow the instructions below under "System Restore" or, if unable, under "Startup Repair":
