Hello Guys . I have an All in One PC Asus . this morning it's running just fine . FYI this morning i extract some files from CD Games to my D partition . it took so long so i left my computer and went to slept . when i awake about 4 hours later, my asus is on sleeping mode but cant turn on , so i press the restart button (atm i forgot that im extracting files from CD). when it turns on, the "Reboot and Select proper Boot device or Insert Boot Media in selected boot Device and press a key" appear . so i check my BIOS . voila ! theres only my DVD RAM that appears in my boot options priorities. ive tried to set it default but nothing good comes . my internal hdd isnt detected . ive open my All in One casing and trying to tighten all the screws but still nihil . can anyone kindly help me to giving solution?i wonder if its because my extracting things using winRAR Thank You !
