winload.exe digital signature cannot be verified error code:0xc0000428

I want to dual boot windows 7 and windows 10.

I have windows 7 installed on my C drive. (disk manage image attached)

Win 10 (D drive) where I want to install windows 10.

IN installation process:
"Getting files ready for installation" completes about 25% and then it reboots and shows the error.

In boot option I have
1) Windows setup
2) Windows 7

When I click on option 1(setup), it shows the error and setup cannot from that point progress.

I have no problem booting and running windows 7(option 2).

Hmm, maybe the logical partition causes a problem. (You can install on a logical as long as boot files are on primary as far as I know but who knows :)).

Is the iso in good shape? Any memory issues?

No problem with iso.

Even if I try to install on C drive it gives same error.

In BIOS, SATA operation mode AHCI or RAID? Maybe you need pre-install drivers?

No I dont think I need any driver because few months back I was able to install win 10 when it first came out.

Can you tell me reasons behind Windows not able to verify winload.exe????

I am able to overwrite win7 on c drive with win7 only but cannot overwrite with win8 or win10.
So I think problem is with my installed win7.
