I have vista on my primary computer the laptops run on xp and I cant network with the xp laptopots in the house with vista as the main computer on the modem and router. Wjy? so I thought I would install xp over vista. I want to install xp, so I went into SETUP and i made my cd drive the primary drive and hd as secondary in order to boot off the xp cd, well when I got to the windows install screen said NO HD. So I went back and made the HD primary and cd secondary. I cant run xp from the cd (merely insertng and installing) any ideas? what am I doing wrong? thanks
