1st thing I tried was the Automatic Repair from the Win8 Recovery startup USB key. Unfortunately the Automatic Repair did not succeed.
I was able to fix the MBR though. By opening a console, using: 'bootrec /fixmbr', but the following command failed: 'bootrec /fixboot', it replied: 'The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted'. Additionally, I proceded to try: 'bcdedit /set {default} device partition=c', but I got this: 'The boot configuration data store could not be opened. The system cannot find the file specified'.
Btw, in case some background info could help: My booting files got messed up as a result of attempting to setup a dual boot (Win8 + Ubuntu).
I hope this give you enough info to figure out what should be my next step.

Update:
I went to NeoSmart's "Fixing the Windows Bootloader via the setup DVD" webpage (https://neosmart.net/wiki/recovering-windows-bootloader) and followed their step #3 (Nuclear Holocaust). I was able to do the 1st 3 commands:
attrib -h -s C:\boot\BCD
del C:\boot\BCD
bcdedit /createstore c:\boot\bcd.temp

But got stuck at the following one:
bcdedit.exe /store c:\boot\bcd.temp /create {bootmgr} /d "Windows Boot Manager"

It said something along the lines of the "parameter not being good". I suppose it means that the following part was the problem:

/create {bootmgr} /d "Windows Boot Manager"

Btw, I noticed this instructions were made specifically for Vista. I hope someone can say that this parameter did change for Windows 8.1 and that the new parameter should be: blah blah blah...

I must admit, I've been trying to fix this for over a week now, by now I'm feeling at the border of quiting fixing these booting files and just try to go the Restore way with one of the Restore files I made before.

What do you think guys? Any hope?

Thanks in advance guys :)

Finally got Win8.1 back!
I just fixed the booting files, then rebuilt the BCD =
bootrec /fixboot
bootrec /rebuildBCD

THat did it!

Now I've got to learn how to back up these booting files I guess.
