ok so i just bought a new 80gb hardrive cause i was running low on space in my 40gb one and i copied everything i had on my old one to my new one because i heard it might help the preformance to run on a new drive and then pretty much deleted everything i had on my old one, i use my new drive to boot but my comp still thinks c drive is the main drive. so my question is how do i change my new drive so it is the main drive so it doesnt keep asking me to locate things like microsoft publisher?.
