0xc0000225 Error when installing Windows 7 (Dual Boot)

Other than my windows 10, I installed a Windows 7 (dual boot) on my laptop. Then recently, windows 10 updated automatically making my installed windows 7 corrupted. As I tried choosing Windows 7 as the OS in the boot screen it showed this error:

So what I did is, I deleted the partition (via right-clicking My Computer then Manage) where that Windows 7 was installed and installed the same installer I used for windows 7. But it is no use cause this error kept showing up. Windows 10 is fine, no problem. I bought a new windows 7 CD installer and it still has that error. What seems to be the problem?
