Windows 8 won't boot, BCD error


My Windows 8 laptop has a boot problem. When Windows tries to boot, I get this error message:


Boot configuration data is missing
File: \BCD
Error code: 0xc0000034

So as suggested I booted to the console and tried:


bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

After the last command I got:


Total identified win installations:1
[1] C:\Windows
Add installation to boot list?

I typed y so I want to add installation, but got a reply:


The requested system device cannot be found.

As a solution I found a diskpart - select and activate OS partition, so I selected OS partition and typed:


active

I got a reply that:


The selected disk is not a fixed MBR disk.
The active command can only be used on fixed MBR disks.

How to fix this problem, to get Windows 8 boot properly? My laptop is a repair of a previously working PC.


Answer



When I tried to refresh computer (after no solution found), I get error saying something like:


PC can't be refreshed, because your disk is locked.


So I tied to unlock HDD as this tutorial say but with Windows 8 installation disc.


I choose to install, after few seconds error:


Bad serial number ...


I submitted this window by clicking OK button. After submitting I choose


Turn off computer


in Windows installation menu. After turning off and powering up everything was working great, no other steps required
