boot - Hoy do I get my data from Windows 8 back?

I had Windows 8 installed in my HP-PC when I proceeded to install Ubuntu 14.04 to run alongside it. My PC has a 2TB hard drive where Windows 8 and all my data was installed. In order to make the Linux partition I used an external 500GB hard drive and left the 2TB one untouched, but the first time that I ran the Ubuntu installer I made the partitions (4 in total) in the external drive but had to quit due to an emergency at the time, so I reverted the partitions I had made, quit the installer and shut down the PC.
When I turned it on again it automatically opened the GRUB where no Windows 8 option was available, as I ran the Ubuntu installer again it did not find any other OS installed which I found odd but still continued, once again I made the partitions in the external drive, leaving the PC 2TB hard drive untouched and finalized it.

Now whenever I turn on the computer I can't access Windows 8 only Ubuntu 14.04 LTS. I can still see the NTFS partitions are there because I used suds testdisk and I can see them exactly as they were before.
My question is how can I recover Windows 8, or access it, or at least recover my data?
