Boot device error

[goatboyy]

Using an older lenovo with windows 10, whenever I turn it on I get a black screen with a blue box that says "default boot device missing or boot failed. Insert recovery media and hit any key then select 'boot manager' to choose a new boot device or to boot recovery media." I press enter or whatever and then there's a white screen that says "boot option menu (up arrow) and (down arrow) to change option, enter to select and option" but there are no options? If I press esc I get a black screen with "no bootable device -- please restart system"

Most likely the hard drive has failed OR the cable/pw connector is loose. Open the case and reseat ie remove and replace both sata data and pw connectors. If you get the same problem, the drive has probably failed.

What would the connectors look like? Should I attach a picture?

First of all, you have to be comfortable working inside the case. If you do not feel you can do this, take the system to a shop and have them diagnose it for you. Here are pictures of what the data and pw connectors look like;

Before opening the case, remove the pw cord from the rear of the system OR just unplug it from the socket.
Now press the ON button 2~3 times. This removes any residual charge from the pw supply capacitors.
