I am going to buy two separate solid state hard drives, both sata III, 120 GB. I will also have a regular spindle sata II 500 GB used just as data, not to boot from. I want to install Windows 7 32-bit and 64-bit, one version on each solid state hard drive. I want a boot up screen to come up that lets me choose if i want the 32-bit or 64-bit. I also would like to be able to log off on the desktop screen within each version and quickly go to the other hard drive and fully change to that version quickly just in case I need to. How do all of this properly and effectively?
