install operating system on hard drive

[Melissa78]

My computer is saying a boot device is not found. I have a boot device and still can not reinstall the operating system on my desktop.

Hi:

The only suggestion I can offer if you have not tried this already would be to clean install W10 as follows...

You can make a W10 USB flash drive installer with the Microsoft Media Creation Tool, using an 8 GB flash drive using another Windows PC, if your PC is not working.

https://www.microsoft.com/en-us/software-download/windows10

If you are asked to enter a product key during the installation process, select the 'I don't have a product key' option, and W10 will install and automatically activate once you are connected to the internet.

Here are the steps to create the W10 USB flash drive installer...

Select Download tool now, and select Run.If you agree to the license terms, select Accept.

On the What do you want to do? page, select Create installation media for another PC, and then select Next.

Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10. You want 64 bit.

Select which media you want to use:

USB flash drive. Plug in a blank USB flash drive with at least 8GB of space. Any content on the flash drive will be deleted.

After W10 installs, you can install the drivers and available software from your PC's support page.

If you can't install W10 that way, you will most likely need to replace the hard drive.
