I have Windows 8 Pro x64 using UEFI boot and GPT partitions. I put it into hybernation when there was a text "Your PC will restart in 1 day to finish installing security updates" on welcome screen. Next day - it doesn't boot. It shows a light-blue screen:
Recovery
Your PC needs to be repaired
The Boot Configuration Data file is missing some required information
File: \BCD
Error code: 0xc0000034
I have bootable USB with Windows 8. First, I tried to boot from it and "refresh" (i.e. install over existing copy). Automatic installation option refused to do anything, saying something like "you're running setup from installation media. Please, run your local Windows and re-run installation from there". Obviosly, I can't do that - because my installed Win8 refuses to run.
Next, I tried to manual install. This time it refuses to continue because "Can not install Windows on GPT partition" (WTF?).
When I failed refresh option - I tried to repair. All repair options available on menu (except from the one which says it will delete your files - I didn't tried it), all repair options either says that they can't find any issues or that disk with Windows is locked (I have no idea how it can be - I can freely access and modify disk's content after opening command-line).
My final hope was for command line and bcdboot. Running "bcdboot D:\Windows" (my system drive appears as D: when booting from USB flash) yields failure for copying files. However, "bcdboot D:\Windows /s C:" or "bcdboot D:\Windows /s D:" completes successfully. Unfortunately, these didn't help: the error remains the same. I also tries to add /f ALL and /f UEFI options, but these didn't work either.
Now I'm completely run out of ideas. The only option that I see is to re-format the disk and fresh-install Win8...
