I have a Toshiba Sata 5400 ROM 500gb ModelMQ01ABF050 Drive Rev AAD AB00/AM0P1D on a Dell 3340 with originally with Windows 7 and was trying to go to Win 10. This is a students laptop in a Elementary School during a State Testing exam that failed. The laptop came back with a message of NO OPERATING SYSTEM FOUND. Cannot seem to make any headway with this or get anything to work. Even tried imaging a total of 3 times to no avail.....Does anyone have any ideas of what we can try...?
