  1. Ah … but what I want to do is impossible, and the limitation isn’t directly mentioned here … or elsewhere. I want to move a partition to the left so I would have to extend it into unused space on the right and then shrink it to recreate the space, on the left!

    Seems in the Windows Wizard, there’s no option for on which side the shrinkage is to occur. There’s just a ‘generic’ Shrink .. from what I can see on the images above, it’s always on the right side.

  2. Thank you for the guide. It works fine on Windows 7 too. Just at little different, but very simple!
