BSOD when trying to install Windows 7 (0x000000A5)

I get an awesome BSOD when trying to install Windows 7 Ultimate x64 bits. I have Legacy mode right now. My PC is an ASUS ROG STRIX GL553VD.
Here is a screenshot of my problem.


Please help.
I've already updated my BIOS in the official website.
I've already disabled/enabled: CSM Support, PxE, Secure Boot.

Please, help!!

So, now I tried to boot from a DVD. Same error. Please help.

Hi Balta,

Your specs say Win10x64 Pro. Are you trying to install Win7 in place of, dual boot, or what?

Where did you get the Win7x64 Ultimate from?

Did you compare hash for match with your Win7x64 Ultimate?

I am trying to dual boot, also I tried to replace Windows 10 with Windows 7.

You didn't answer all 3 questions so I'll reiterate:

1. Where did you get the Win7x64 Ultimate from?
2. Did you compare hash for match with your Win7x64 Ultimate?
3. Added ?: Dual boot what two OSs

1. It is a official Windows 7 Ultimate disk.
2. How can I do that?
3. Windows 10 and Windows 7.

By the way, just tried the DVD after the USB, got rid of that.
