My laptop was working fine i turned it off . when i turned it on all of a sudden it says ''OPERATION SYSTEM NOT FOUND'' now it wont open no matter how much i try. Please someone help me please....
I recommend you to run diagnostics on the hardware components of the system. To run diagnostics restart the system and at the Dell logo tap the F12 key every two seconds. This will start the One-time boot menu. Using arrow keys select ‘Diagnostics’ and hit enter. This will run diagnostics on the hardware components of the system which may take around 5 minutes. Please reply to this post in case of any error message.
If the test passes, you may consider setting the system to the factory installed state. Please find the link below for instruction:
In case you are unable to perform PC restore, you need to clean install the Operating system. Revert for further assistance.
