I have successfully installed Ubuntu 13.04 dual-booting with Windows 8. It was working for a while, and today I accidentally broke the Windows boot system. Now the system is not booting Windows, but Ubuntu is working normally from Grub2.
I still have access to the Windows filesystem and EasyBCD backup files. The entry Windows 8 UEFI repair was the one that I used to boot Windows 8. Now it tells me, in the "/BCD" there is not valid data or something like that. As I read online, it seems I need to repair the Windows bootloader. Unfortunately, I just got this computer and I didn't create a Windows 8 repair disk. I tried with testdisk, but after "Analyze", this is the result. So, something is off.

Is there any way to get my Windows 8 to boot without wiping my data? Or is there a way to create a Windows 8 repair disk from Ubuntu?
