Hi,
Simply installing the drive should not cause the system not to boot. As
David has mentioned, first check that the drive's jumper is in the correct
position for the location to which you have installed it (master/slave/cable
select). Also, recheck that the cabling is fully seated on both ends. If you
get through the system POST and Vista still fails to load, post back with
the configuration and how the drive is detected in the system BIOS.
