Surface pro 5

I have install fydeos for my surface pro 5 with USB, from the last step, systerm required me to shutdown. I did it then I pressed the power button to turn it on but the below error apprearred: " “Couldn’t find a bootable operating system. Check the Boot configuration to try to fix this”"
Please help to fix it

Did you watch the installation guide? Try to follow the guide, especially for the bios setting part.

Thank you,
I changed the USB and re-done the process then it worked.
But as a result the camera is very bad, and the sound is lower than the original Window. How to fix it?

Nothing you can do. It’s the Linux limitation on surface devices.
