Hello, I have bought the upgrade instalation disc for Windows 7 as I am currently running XP. When I was looking into Windows 7 I was advised that it is best run on an SSD, so I bought one of those too. I am currently using a laptop because I ordered a new PSU too for the new GPU I bought so my computer is currently off awaiting my new parts to arrive today.. My question is, will I have to keep my old HDD in the computer in order to install Windows 7 as it's the upgrade package?...I'd really like to just remove it and start the instalation fresh on my SSD oherwise I assume that I would have to transfer Windows 7 over to the SSD after, then turn off the computer and remove the old HDD, which is a bit of a pain. I don't want the old drive in there beause of the added heat and power consumption. And honestly I have no idea how to transfer Windows 7 from the HDD to he SSD. Can anyone help?...thanks.
