I dropped my laptop last night by mistake, No severe cracks or stuff. But now the dell laptop is showing a black screen with the error message- " no boot device found. press any key to reboot the machine" but then nothing happens. The same message is displayed again and again. I ran a PSA diagnostics and it shows a warning sign on Hard disk and gives a message error message PSA v4228 Error 2000:0155 Hard Drive not installed. The laptop is under warranty. What Further steps I should take to recover my computer from this error. Thank you.
