Well, I have half that size getting fitted with new partitions:
Now I have to wait for the copy, extend the partition to take up the remaining space on the 250 GB disk, do myself a little "sudo apt-update grub". If that doesn't work it's "sudo apt-get install --reinstall grub && sudo grub-install" and THEN "sudo apt-update grub". Then I'll be able to boot right into a much larger partition. Also note that this is a non-destructive process. If it all goes to worms you haven't lost anything and can try again. And this is a free operating system with all free software doing the heavy lifting of expensive Windows alternatives--most of the time doing it better.
It's amazing to have an operating system that trusts the user and isn't afraid to give them micro-control of their own machine.
Half done copying the partition from the smaller hard drive to the larger.....
