My Windows 10 operating system is missing from my all-in-one desktop. All I did was the BIOS update

Product ID is V8P01AA#ABA. HP support assistant on my desktop told me to update the BIOS. As it was doing it my computer gave me the blue screen telling me do you install an operating system.

Hi:

If the operating system is gone as a result of a BIOS update, see if you can repair the situation.

Make a bootable USB installation flash drive using another working windows PC and the media creation tool at the link below.

Make the 64 bit installation media.

Boot from the installation media and when you get to the screen where it indicates Install Windows, on the lower left hand corner of that screen, there will be a repair your computer option.

Try the various repair options.

If that doesn't work, and you have important files you need to recover, boot from the installation media again, and this time select the Install Windows option.

When you get to the part that asks, where do you want to install Windows, install it over the current windows partition, and it will create a Windows.old folder.

After W10 has completed installing, you can explore the Windows.old folder, find your old user profile and copy any files and folders you need onto a portable hard drive.

Once you have done that, you can go back and use the HP cloud recovery tool to create a bootable USB recovery drive that will reinstall W10, the drivers and the software that originally came with your PC.

Here is an info link for how to use that utility...

If you don't have any personal files you need to recover, you can skip to making the recovery media with the cloud recovery tool and reinstall W10.
