To transfer Windows 8.1 to a new hard drive is extremely simple the hardest part would be installing the hard drive. Copying Windows 8.1 to a new HDD will eventually save a hell lot of time, you don’t have to install all programs and configure settings from scratch.

9. Once done it will provide you with a brief explanation in case you are keeping both drives. In my case I’m only keeping the new hard drive so all we have to do is just turn off the computer, remove the source disk, and keep the new hard drive which is the destination Drive and turn the computer back on.
9. In case you didn’t check mark Use all available space for the OS partition on the paragon cloning wizard and you wish to use the full space of the hard drive, you could go to Disk management and re-claim that partition.
