Hello and need an question answered

Disable the Anti-Aliasing.

In 2.5 Beta, second button from the left.

In 2.1, between the grid and the rulers, at the left size of the zoom tools.

Or Tools Menu > Anti-Aliasing.

Disabling anti-aliasing doesn't affect how the Move Selected Pixels tool renders, however. For v2.5 what he's asking for isn't directly possible.

You can, however, probably trick things by Image->Resize-ing the image to be larger using Nearest Neighbor resampling (300% ought to do it), doing the rotation, and then resizing back to the original size (again using Nearest Neighbor).
