I screwed up my Windows 8.1 boot with Easybcd. I checked some box that said count down from 5 seconds in the edit boot section now if I boot in UEFI boot it says windows cannot boot insert repair disk and if you don't have the repair disk contact manufacturer. If I boot in CSM boot mode I can get to Debian 8 grub menu but windows is not on it. I want to use Grub customizer to be able to boot windows and maybe have windows show up on the Debian grub menu if it is not to risky. I cant even see window with the grub customizer program.
