Accidentally Deleted OS

[SomeGuy123]

Product Name: HP Pavilion Laptop

Product Number : 4AL49UA#ABA

I was doing a system recovery but accidentally turned it off and in doing so deleted my OS. I need help on fixing this issue.  Whenever I turn on my laptop, it just shows a black screen that says "Boot Device Not Found" and "Hard Disk (3FO)". If I press F2 for system diagnostics, I get the "HP PC Hardare Diagnostics UEFI" screen but it's in Version 1.24.0.0 - BIOS. So im completely puzzled on how to fix my computer. I have a drive that supposedly contains the Windows 10 installation media. Please help.

The HP Recovery function starts by reformatting and erasing the entire drive -- including the recovery files.  So now, you would have to use external media to do the restore.

Since your PC can not successfully do an internal factory reset, your ways to accomplish this are the following:
- Factory reset using external HP image you make
- Factory reset using external HP image you buy

Each of these is discussed in some detail below ...

---------- Factory reset using external HP image you make ----------
HP provides a Cloud Recovery tool that you can use, together with a 32GB USB stick, to create your on HP reset media.

Here is the link: https://support.hp.com/us-en/document/c06162205

This works the same as the factory reset described above.

---------- Factory reset using external HP image you buy ----------
For those PCs not supported by the Cloud Recovery, in some cases, HP offers Recover Media for sale. This can not be downloaded; instead, it must be ordered from HP.

HP Recovery Media 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.

In some cases, you may be able to order a USB stick instead of disks.

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 &quot;Update&quot;.<br><br>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 &quot;+&quot; 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.

HP contact info: https://support.hp.com/us-en/contact-hp?openCLC=true

If HP no longer carries the media you need, another site you should check for HP Recovery Media is: http://www.computersurgeons.com/

These work the same as the factory reset described above.
