My wife has a Dell Inspiron with Win 8. She was playing some game on Facebook and the computer froze up, so she turned the computer off. Upon restarting it gave the command... Checking media [fail] Checking media No boot device found. Press any key to reboot the machine_ I did some searching around here and found out how to do an F2 I believe it was and did a diagnostic. It says that the harddrive is disconnected...I stopped there. (Called Dell too, but apparently the tech support has run out). Help please...and thanx in advance.
