Hello @Ab_2-4, and welcome to the HP Support Community!

Thanks for posting your question. I'm here to help you get things back on track.

If your HP Notebook shows a message like “Operating System not found” or “No bootable device”, it means Windows is missing or corrupted. Here's how to resolve it:

Option 1: Install Windows Using HP Cloud Recovery Tool (Recommended for HP Factory Image)

If your notebook supports HP Cloud Recovery, this will reinstall Windows along with drivers and HP software.

Steps:

• On another working Windows PC, download the HP Cloud Recovery Tool: HP Consumer PCs - Using the HP Cloud Recovery Tool in Windows 11 and 10 | HP® Support
• Insert a USB drive (at least 32GB) and run the tool to create recovery media.
• Plug the USB into your HP Notebook and turn it on. Press Esc repeatedly, then F9 to open Boot Menu.
• Select the USB drive and follow on-screen instructions to reinstall Windows.

Option 2: Install Windows Using Microsoft Media Creation Tool

If HP Cloud Recovery isn’t available, you can install a fresh copy of Windows.

Steps:

• On another PC, go to: Download Windows 11
• Use the Media Creation Tool to create a bootable USB (8GB or more).
• Plug the USB into your HP Notebook, press Esc > F9, and boot from USB.
• Follow the installation steps. You may need to delete existing partitions during setup.

Additional Notes:

• If your notebook came with Windows pre-installed, the license key is embedded in the BIOS and will activate automatically.
• After installation, use HP Support Assistant to install drivers: HP Support Assistant | HP® Support

I hope the information shared has been useful and resolves your concern.

Wishing you a smooth and hassle-free experience ahead!

Thanks so much for your detailed answer, I appreciate the effort you put into this. Unfortunately I do not have access to any other computer, I did try at local library but they do not support this. I don't understand how this has happened but I have tried with other things which have not worked. I am very disappointed as it is only 2 years old and has not been used very much. So if anyone has any other options I'd love to hear. Thanks so much again for responding.
