Answer 1

I had the same problem... I used Boot-Repair, that helped a lot

sudo add-apt-repository ppa:yannubuntu/boot-repair  
sudo apt-get update
sudo apt-get install boot-repair

Then run Boot-Repair and you should be able to start Windows.

Answer 2

I did a quick search and came across this:

Invalid EFI file path

I hope it helps.
