My system came with a 2TB HDD drive. I am only using 120GB on it. I want to buy a 500GB SSD to replace this with. How hard will it be to cone the HDD and use the new SSD? I have been searching this and have read a lot of horror stories in trying to do this. If there is any problems is it possible to use a windows 10 ISO and just install my windows only and start from scratch? Any help would be greatly appreciated.
