When I boot to Windows 8.1 I get:
Boot Device Not Found
Boot-error-2-Small.jpg


These are the partitions on disk 1:

These are the boot options:

How can I fix this to boot to the C: drive?

I have run these commands:

NOTE: Do not run these cmds on your computer unless you know what you are doing. These are created specifically for my computer.

diskpart
DISKPART> list disk
DISKPART> select disk 0
DISKPART> list volume

# find your system partition with fat32 file system. Here to assume it as volume 2.
DISKPART> select volume 2
# To assign drive letter.
# If you want to remove drive letter, use remove command.
DISKPART> assign letter=b:
# To terminate diskpart command.
DISKPART> exit

# Now, you sould move to b:\EFI\Microsoft\Boot\, as windows stores BCD in this folder.
cd /d b:\EFI\Microsoft\Boot\
# this is not necessary.
ren BCD BCD.bak
# To write a new bootsector on your system partition.
bootrec /fixboot
# If your windows running, you should do from here.
# To create BCD store. "/f ALL" is to update BIOS setting including UEFI firmware/NVRAM.
# It might be sense only typing "bcdboot c:\Windows".
bcdboot c:\Windows /l en-us /s b: /f ALL

I get an error saying:
Failure when attempting to copy boot files
