I built my PC last week, first one I've done in over 10 yrs. Everything went smoothly other than copying windows over. I used Macrium Reflect to copy from my old mechanical drive to my new SSD. The SSD is 1TB and the older drive is 250gb. It must have partitioned the drive because all I see now is, windows showing my new 1TB SSD is 250GB. How can I access the rest of my storage? Also windows is telling me my product ID is non existent.
