but turn ON alone "Non-System disk or disk error replace and strike any key when ready"

I upgraded to windows 10 Pro from 8.1 Pro.

The only problem...

when some nights Turn Off PC I find it in the morning ON [not me open - but turn ON alone]

with the words in a black screen

"Non-System disk or disk error

replace and strike any key when ready"

Then pressing Turn Off/ON PC goes OFF and when press again Turn ON/Off PC starts NORMALLY... WHAT TO DO????

THINKING MIGRATE TO SSD.

AND

ALSO WHEN IN MAY 2015 PUT FRESH WINDOWS 8.1 I PUT A NEW HDD SO HDD IS NEW.
