A few nights ago our electricity went out just for a few minutes. When the lights came back on I turned the computer on.. What was on the screen at that time was "Preparing Automatic Repair". I checked on YouTube and found someone explaining how to fix my problem. Now I have a blue box on the screen that says "Boot device not found. Please install an operating system on your hard disk". That's as far as the YouTube helped.. I can't do anything with my computer. No app screen, no start button, nothing except the blue box. Can someone please help me.

> Boot device not found.


You have a serious problem -- the computer cannot read the disk-drive, to load Windows from the disk-drive.


If the HP Warranty is still valid, HP will repair your computer, by replacing the disk-drive, and giving you a copy of Windows.


If the HP Warranty has expired, then, for a fee, HP will repair your computer, as would any qualified local computer technician. You can either contact HP Support, to get the HP-customized version of Windows 10, to install onto a new disk-drive.  Or, see: Download Windows 10 (microsoft.com) to download the "generic" version of Windows 10. If you do, then use the HP Support Assistant to add the HP-specific device-drivers for your HP-specific hardware components.

the hard drive is defective
It can continue to operate for a certain time, but it can definitively break down, if it is not already the case!
If possible, save personal data
Try a full reinstall
Be careful even if it works, it may permanently break down, save the data regularly.
This may allow you to use the computer while you find a hard drive!

You can try to help yourself with this tutorial (sorry not fully translated)

que faire en cas d' erreur / échec dst du disque dur - HP Support Community - 7338574

 Using the HP Cloud Recovery Tool (Windows 10, 7)

You can try several things in order to try to recover your data

You can try a bootable cd / dvd type live cd (linux)



you can try removing the hard drive, in order to connect it to another computer internally, or with a usb adapter!

If your disk is not completely out of order, this gives you a small chance
