I have the win7 beta on dvd and getting the computer shop to install a 2nd hard drive 320GB in size. Should I make a partition of 30GB on that drive and install the beta there? what benefit will there be having a partition or is there none. And another question, if and when Microsoft releases the full version on win7 for public sale, what will happen to the beta? I mean, does that win7 beta get overwritten by future installs of win7 or do u have to format that disk clean first before any new install.
