Have Win XP-32 bit on current primary WD Raptor 74 gig HD. Want to put in a new, second Raptor HD with Win7-64 bit as a 'dual-boot' system. I have the Win7-RC on a DVD now. System in 'sig'. \n \nCould someone take me thru the installation process in very detailed steps. I will appreciate it.\n \nThanks.
