Thank you a head of time for your generosity and skills.
It lookes as if I have a missing UEFI "boot" sectore. All I get is a black screen after the manufacturer boot screen. (please refer to image)
What I have tried:
1. Bootrec fix, etc attempts
4. Windows 8 rescue disk and auto fix
5. Third part rescue live disk to do a chkdsk (please refer to image)
None of these worked. At one point the bootrec worked fine in all the steps and then it didn't. And the same thing with diskpart. I see that there is one partition with errors. (please refer to image.)
What do I do to fix the EFI?
Thank you very much for your time and efforts!
