Newer HP h8-1039 pre-installed Win 7 Home 64 bit. No disc as Win 7 pre-installed and partitioned recovery on HDD. Want to install 2nd. new HDD and install XP Pro from disc to new HDD to play older 32 bit games. Like Win 7 as default with option to switch to XP on start-up to play old games. Will I need EZBCD or certain sequence on MOBO to plug in the 2 SATA cords? Not too savvy so go slow.
but if ya still wanna doi the extra HD thing.....unplug ya existing HD data cable, install old windows.... to the windows update / reboot dance 8 or 9 times then when done, turn machine off and reconnect data cable from original drive....decide which ti boot from via BIOS
