I'm sorry to posting too late just busy with college stuff, Anyway i guess you are right about the Check Compatibility but it didn't show my any "Press any key to boot the CD or DVD" and it didn't start from Boot and that's why i try this way.
So i read this page Clean Install Windows 7 again & i find that in some PC you have to click any key right before window start and it did start from boot it say Window loading files. After Window loading files This
It was working fine but it stuck here
about 2/3 then it restart the window that happen 5 times so i give up.
I try today again and find the problem it was when the window starts it ask me to "Press any key to boot the CD or DVD" but i didn't press any key this time and it took to this
so i got my Window 7 Pro back
Oops i forget you ask me about the make of my PC, it's Lenovo business & gaming loptop. I'm sorry i am new to PC world & i barley use my PC. You guys are awesome helping so many people around the world.
