I have a new Dell Vostro 3750 64-bit notebook, and after 3 months of unbelivably frustrating and agonizing experience with Win 7 and its XP Mode, I want to install plain old 32-bit Windows XP even at the cost of sacrificing the installed 8 GB memory. While attempting to install Win XP (both x32 and x64) it crashes with a blue screen. Somewhere on the net I read that on most branded computers this is deliberately done by the manufacturers who somehow cripple SATA drivers to prevent installation of other OS's. Any help?
