I bought an SSD and downloaded windows on it using the disk. I unplugged my HDD and plugged the SSD in for Windows to install. When it was done I plugged back in the HDD and SSD at the same time, but only things on the SSD were showing up. So it was completely blank. It said my HDD was connected but none of the files I had were on my desktop where they should be. Did I do something wrong?
