Dear Customer, Welcome and Thank You for posting your query on HP Support Forum It looks like your Notebook is showing "No Boot Device Found" error messageWe will surely assist you with this issue This error message also means that the hard drive is so dead, that the notebook doesn't even know it has one installed. You need to replace the hard drive and reinstall the operating system. If you intend to repair the PC, try removing and reseating the hard drive before buying another one. Maybe the contacts are loose or oxidized The "Hard Disk [3F0] / Boot Device not found" Error message could be because of 3 things as shown below: 1. The Hard Drive or the Partition Structure of the Hard Drive could be corrupted or bad2. We need to check if the Hard Drive Data Cable which connects to the System Board has gone faulty or not. If yes we need to replace the Hard Drive Data Cable3. Bad SATA Controller on the System Board replaces the System Board or Notebook To start with please check if you are able to access BIOS to test the Hard Drive Please Click on the below shown link to perform the Hard Drive Testhttp://h10025.www1.hp.com/ewfrf/wc/document?docname=c00439024&cc=us&dlc=en&lc=en&product=3816360&tmp_track_link=ot_search#N32 If you are unable to access BIOS please remove the Hard Drive and then try to access theBIOS again. Once you remove the Hard Drive boot the Notebook again and press F10 to access the BIOS. If you are able to access BIOS then the Hard Drive is bad Please perform the below shown step if required:Remove the Hard Drive from you Notebook and test it out on a different Notebook. Incase if you are still getting the same error that confirms the fault with Hard Drive Incase if the Hard Drive works normal on a different Notebook please contact HP to get your Notebook diagnosed by an HP Certified Engineer Note: Just to let you know most of the Notebooks have the Hard Drive & SATA Cable built in which cannot be replaced unless we replace the whole Notebook You can Check your warranty Here to verify the status and Click Here to order a new Hard Drive  Hope this helps, for any further queries reply to the post and feel free to join us again  **Click the White Thumbs Up Button on the right to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,K N R KAlthough I am an HP employee, I am speaking for myself and not for HP
