Suppose I have my Windows 7 Pro 64-bit ISO setup contents copied to a boot-able USB flash drive.
Suppose I modified it by copying the folder efi/microsoft/boot, and pasting it to efi/ to make my windows boot on UEFI systems. (as said on this tutorial, for 64-bit)

Question:
Would my UEFI-ied Windows 7 Setup work on other BIOS systems?
