I am trying to install Windows 7 (64 bit) on my Acer desktop. I have a 64 bit processor. When I boot with the Windows 7 disc to install, it doesn't prompt me to choose between 64 bit or 32 bit and ends up installing the 32 bit version. How do I install the 64 bit Windows 7?
Processor - AMD Phenom 9500 2.20Ghz (Quad core)
RAM - 4 GB
