What exactly is the point of this thread? Are you asking how to install Vista in this situation? The thread title sounds more like a tutorial rather than asking a question. I'll leave it open for now since I'm thinking that might be the case. If you're asking a question, please clarify that. Thank you.

u wrong uefi class 3 exists

I found the answer myself

https://wiki.osdev.org/UEFI#UEFI_class_0-3_and_CSM

Calling it UEFI class 3 is incorrect, as it clearly indicates a class 0 is BIOS and thus cannot be UEFI.

I don't see why it would matter. Vista SP1 x64 should support a Class 3 system. Just use boot menu and see if the DVD has the UEFI prefix.

YOU VERY WRONG ITS SAYS "A class 3 machine is a UEFI system that does not support CSM. UEFI class 3 machines only run UEFI applications and do not implement CSM for backwards compatibility with legacy bootloaders."
