I chose the Linux forum because I am on OpenSuse right now, and I am trying to fix my issue from Linux.

I think something happened to my Windows 8 EFI because Grub doesn't see the system and does not let me get into it. Something may have gotten corrupted. I tried adding the option to Grub to get into Win8 but it just cannot find any EFI. There's only Linux. I tried various tools to check if my hdd is corrupted but no, they show everything is all right. I can access all my Windows disks from Linux too.

Here is my log from Boot Info:

I really don't know which way to go after this problem.
Is it really the case of corrupted EFI? Or something else all together?
I would really appreciate if someone could point me in the right direction.

I feel that maybe I have not provided enough information so here is more:

I am on Windows 8.1.
I was moving homes.
My laptop has fallen down. It got a bit roughed up but seemed to be working the same. Two days later, I move it from one table to the other it goes into BSOD. I restart hoping for the best. I get to the win login screen, after login black screen and only mouse visible.

Ok, trying to repair with win recovery tools. They say windows is blocked/locked. Cant do anything. Similair errors show up in cmd when I try to rebuildbcd.

Now, im using my linux because it works well, and I can see that all my drives are working fine.

Whenever I try to get into Windows Im welcomed with BSOD saying error code: 0xc000000f. Your boot configuration data is missing or contains errors. File: EFI/Microsoft/boot/bcd

Maybe this thread is more appropriate to the win8 forum section after all? But i tried a lot troubleshhoting ideas for Windows and came emptyhanded...

So, finally I managed to deal with the problem.

I have dual-boot with Linux and to make that work I have got two efi partitions.
One for Linux, one for Windows.

And suddenly, Windows decided that it's not all right.

None of the win recovery tricks worked either, because the software for repairing windows was confused by the fact that there are two efi partitions.

So the solution here helped me:

I changed the id of my linux efi partition and things started moving forward.

After that, I just went and did everything in the recovery tools possible, did 'sfc /scannow' after I restarted a couple times (this one didn't want to work either). And it seems to be back in working condition.

Thanks!
