Just wondering how this is going to go. Right now my comp is running XP Pro which i obtained from my IT department. Im a federal employee so the disc i have is a federal corporate license. Today i purchased W7 Pro and a new 1Tb hard drive. Im goint to make my old hard drive backup storage and put the W7 OS on the new drive. Whats the best way to go about it? When i install the new hard drive and boot from the W7 disc is it just going to prompt me to put in the XP disc? Or does it just ask for a valid XP license key? Everytime i have installed this XP on a new comp it never asks me for a CD key...i think it has something to do with the fact it is a government license and is unlimited regarding the number of comps it can be put on. If i need a key i guess ill have to wait till i get back to work and get one from the IT department.
