startup screen is black and says boot device not found.

[mya01107]

startup screen is black and when i click F2 and check Hard Drive Check it says there is no hard drive installed. then it tells me to check that the power and data cables are connected properly. every time i exit it either leads me back to the same boot device not found black page or it lets me sign in and it restarts all over again

That error code means your disk drive is failing and needs to be replaced.

Once you have the replacement drive, read the information below about HP Could Recovery to be used to restore your PC to working condition:

If your PC is a 2016 model or newer, you should see if you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC. The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC. Here is the link: https://support.hp.com/us-en/document/c06162205

--------------------------------

If the HP Cloud Recovery is not available or does not work, you may have to look into ordering HP Recovery Media -- which is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utilities. You have to order these from HP; they can not be downloaded.

You can look online for Recovery Media starting with the linked paged: http://support.hp.com/us-en/drivers

Once there, input your Product name or number. On your Software and Drivers Download page, select your Operating System and and Version. Click "Update"

If HP Recovery Media is available for your machine, down near the bottom of the page, you will see an entry for Order Recovery Media-CD/DVD/USB. Click the + symbol to expand that entry and click on Order Media for details.

Or, if you prefer, you can do the same by contacting HP Customer Support:
