Need to copy a drive to another? Moving Windows from a HDD to an SSD, or just backing up? This video shows you how to mount 2 drives, and copy files and partitions between them easily.
This video is not sponsored, and any software to copy partitions should work the same. I used this to move my Windows installation from a smaller drive to a larger one. This video was recorded a while ago, but still works today.
