Thank you for joining in on the HP Support Forums and Welcome! This is a great place to ask questions, find solutions and get help from others in the community! I read your post on the HP Support Forums.
I watched the video you had posted on YouTube. If I understand correctly, you upgraded to Windows 10 and now you are getting an error that says "The Boot Configuration Data for your PC is missing or contains errors".
The error code that came up with this specific error is: 0xc0000185. I seen/heard that you were trying different options to try and get the Notebook to work.
If you require further assistance, I would be more than happy to help! Please just re-post with the information required from above. Please let me know the detailed results of the troubleshooting steps provided.
When we have come to a resolution, please share what worked for you with others by marking the appropriate post as an Accepted Solution. If you would like to show your appreciation for my efforts today, please take a second to click the Thumbs Up button below.
