To fix the problem:

1. First Load Windows ISO from Windows 7 or Server 2008 R2 and select “Repair from Command Prompt”
2. Open Diskpart and make problematic partition Active: list disk, select disk X, list partition, select partition Y, active, exit
3. Open bcdedit and you should get something like this:

Windows Boot Loader
——————-
identifier {default}
device unknown <===0xc000000e problem!
path \Windows\system32\winload.exe
[..]
osdevice unknown <===0xc000000e problem!
[...]

4. Enter these commands:

bcdedit /set {default} device partition=X:
bcdedit /set {default} osdevice partition=X:
bcdedit

Where X: – drive letter with your problematic OS in Windows during recovery. You can find it by opening notepad and pressing save

5. Reboot
