Updated to Windows 10 killed my Debian GRUB (U)EFI Boot

After the Windows 8 -> Windows 10 Upgrade the Debian testing UEFI Grub2 only showed it's rescue shell. On Debian, I use full disc encryption and have a seperate boot partition - here is how I fixed my Grub without using some LiveCD or Live USB:

On the Grub rescue shell, enter the following - in case you don't know which partition holds what, you can also try > ls (hd0,gpt7)/ [Enter] to get some content information. I knew that number 7 was my dedicated boot partition and number 8 the encrypted root file system.
