Upgrade from Home to Pro
My desktop OS is Win 7 Pro 32-bit installed from a retail disk. I just purchased a laptop with reinstalled Win 7 Home Premium 64 bit. I want to install the Pro version to the laptop from the retail disks which has disks for both 32 & 64 bit versions. How can I make the upgrade? Does it make any difference if I use 32 or 64 bit for the upgrade? Note: the laptop does not have a cd drive and I will need to purchase an external drive. Could this pose an installation problem?
