MacBook Pro mid 2012 screen boot glitch when booting into Windows 7

I am attempting to use Windows 7 for overall looks. (I am aware of the risks and I don‘t care.) However, whenever I attempt to boot into the partition that I installed it on, The following occurs. 1. The screen goes black. 2. Next, the top of the screen creates this strange loading flickering effect. 3. Finally, it stops and reverts to a black screen. I have Open Core installed and that didn't change the boot process. Even without it the same results occur. I have used Windows 7 with and without UEFI booting. I suspect something is wrong with the recovery drive. If someone can, please respond, because I haven't seen anyone else experience this. The strangest part is that Windows 7 used to work and stopped after I uninstalled it once. Here‘s a an image for description: Heres another image with stock bootloader
