So right now im running on a single 500g HDD and its almost out of space. Im looking to get a WD black 1tb pretty soon but im confused as to how to approach this. What i want to do is, format my 500g and use it strictly for media, then do a fresh install my UPGRADE version of Win7 on the 1tb. I dont know how the upgrade disc works. I dont know if i can just install the 1tb, format it, format the 500g, then boot from the disc and install to the 1tb? or install the 1tb, copy over the 500g to it, wipe the 500g, then install win7. am I thinking too hard or is there a simpler method that im just not seeing?
