This question:
0xc000000f BCD error in windows 10... Nothings working
was marked as duplicate by several members.
I think it is not an exact duplicate as there are differences in Windows 7 and Windows 10 boot process. At least there is the new "Metro" or graphical/immersive boot menu which is implemented through several dll-files non-existent in Windows 7. There are also new BCD elements specific to Windows 10, not to mention widely used UEFI firmware on newer computers.
As a consequence Windows 10 boot manager is different and some boot errors are different. You cannot transfer one to one old solutions to boot problems for Windows 7 to Windows 10. There are also changes in Windows loader, kernel etc.
