Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!
I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP ENVY 6-1202eo Ultrabook and issues with starting. I recommend to restore the BIOS defaults.You could restore the BIOS with this document selecting the reloading the BIOS default settings. That way it will look at the Hardware installed on the Notebook.
If that is not a help upon first starting the Notebook press and hold Windows key and b. Just keep holding it. Once your sure nothing is happening restart the Notebook. This should restore the last configuration of the BIOS.
Try running a system test to see if all is working ok. Please let me know how this goes.
