Window 7 sp1 not gettin installed after using boot camp 5.0 on mountain lion on macbook pro 2009 mid

Hi there everyone !

I am facing a strange problem. I downloaded a Mountain lion Iso from internet ( ver 10.8.3) , which i made a USB disk bootable from Lion Disk Maker software. I did a clean installation. I want to install Window 7 Sp2 Ultimate 64 bit. I have already installed easily through boot camp but this time when i insert the window 7 disk and it makes partition and after restart its all black screen for which i waited may be the installer starts but it did not.

I tried to try the option key trick but there i couldnt see the Boot Camp drive which partition makes and also the when Window 7 disk appear and i click it , It restarts and again the same black screen 😢. Please help me out , I have to use windows as I have migrated from windows.
