I clean installed Windows 10 to a brand new SDD yesterday in my pc which has had everything stored on my current HDD. I followed guides instructing me to back up my current HDD to an external drive which I did and unplug the HDD while installing the new SSD with Windows 10. I did all that and plugged my HDD back in to restore my old files but after several attempts I still can't get it right. I know the files are securely on the external drive but I think there's an issue with assigning the files back into the right place. Initially I used the default option of letting the files go back to their origin but that didn't work. I noticed that the SSD took (C which I know my HDD used to follow but now that is (D and I don't know how to fix this.
