I thank yu for all the info you give. I was wondering if there is a way to know what running processes are necessary in Vista before I start sutting them down? Also, If I am going to install a second OS on another ahdr drive in my computer, do I need to disable other hard drives before installation? I hope someone will respond to this question at 2nthecountry@bellsouth.ne or let me know how to retrieve the answer. Thank YOU eDWARD
