dual boot - Grub update can't detect hybernating Windows partition

I've kinda wound myself into some weird paradox.




I have Windows 8.1 and Ubuntu 14.04 installed on two different HDs. Both are 64 bit. I just recently deleted and reinstalled Ubuntu, but update-grub and os-prober can't find my windows partition. I thought maybe it was damaged so I ran ntfsfix /dev/sda2 (where Windows is installed) and got the error Windows is hibernated, refused to mount.



I've already tried going into my BIOS/UEFI settings on my motherboard, but my motherboard doesn't detect the drive anymore either. I can still see the drive when I run gdisk or gparted. I tried boot-repair, but that actually made ubuntu completely unbootable. I had to chroot from my live USB and reinstall Grub2 so I could even ask this question. So all this together leaves me in between a rock and a hard place.



How do I boot into Windows to unhibernate Windows so grub2 can detect Windows and add Windows as a bootable option in grub?
