Hi again, King Hebra!

To rebuild the boot configuration data (BCD) follow these steps:
1/ Put the Windows installation disk in the disk drive, and then start the computer.
2/ Press a key when the message Press any key to boot from CD or DVD appears.
3/ If your PC does not detect the media automatically
4/ Select a language, a time, a currency, a keyboard or another input method, and then click Next.
5/ Click Repair your computer.
6/ Click the operating system that you want to repair, and then click Next.
7/ In the System Recovery Options dialog box, click Command Prompt.
8/ Type Bootrec /RebuildBcd, and then press...
Hey there, King Hebra!

Well, there are several ways to fix this issue. You are going to need just the Windows installation CD/DVD.
- One is to run the Startup Repair from the recovery options.
- Another one is to rebuild the boot configuration data (BCD).
- Your third option is to run System Restore.
- If you don't have the Windows Recovery/Installation, and you have a pre-installed Startup Repair on your computer, you can use that to fix the issue.
Here's a link that explains how to perform all these methods step by step: https://support.microsoft.com/kb/2622803

Hope this helps you! :)

Another thing that you can try to fix the problem is TestDisk, it might fix the MFT error and rebuild the boot sector.
It won't hurt to give it a try, I guess.

Good luck! Keep me posted with the results!
