Welcome to HP Forums,
This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂
As I understand, your notebook does not boot to Windows and gives an error message.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
When was the last time it was working fine?
Could you share a picture of the error message?
Did you run a system test?
Once I have the information, I will help you further. In the meanwhile you could refer to this document: Boot Device Not Found Error or Hard Drive Not Detected and run a hard drive test follow steps from the document: Testing using HP Basic System Diagnostics
Keep me posted,
Have a great day 🙂
