I recently tried to install Ubuntu 16.04 alongside with Windows 10 in Dual-Boot. Unfortunately, only the Linux Bootloader showed on startup and when I chose to start windows, it got stuck in an endless loading screen. I then checked some forums to fix the problem, something went wrong. Now, I get the message "Boot Device Not Found".

With bootrec /scanos I get 0 windows installations.
bootrec /fixboot doesn't work.

I got an HP spectre x360
Model: 13-4103ng

Does anybody have an Idea?
 


Boot order is correct, but all the entries are "black".
