My 120GB SSD I just ordered has just arrived at the door. I don't know how I would get the data off of my current hard drive to my SSD. My hard drive has 430GB free of space. I believe the only way to get data on my new SSD would be to completely re-install Windows? Since I don't have a Windows OS downloaded onto a USB, or have a disk of it, I'm worried that I might run into some errors trying to re-install Windows.
