This question already has an answer here:

I had a blinking-cursor black screen freeze on my dual-boot Freya/Windows 8.1 system.

I have restored the grub and can recover my Windows files. How can I restore Windows 8.1 to healthy dual-boot with GRUB in charge?

Here is the Boot Issues file: Boot-Repair BootInfo summary Working through "Boot-Repair" utility: BootInfo

    Resolved just now by running "Boot-Repair" tool! (Installed from Software Centre). Great little app to know about. – Richard Bruce Gordon Aug 19 '15 at 16:52

Run sudo update-grub in terminal after booting into elementary. This should detect your Windows 8.1 partition and automatically add it to grub.
