Why won't it let me expand the disk?

Question

Windows

Hey! I don't understand why the next button is disabled.
And if you also select a piece from another disk, then it becomes active. But I need to increase at the expense of one physical disk. What don't like windows?

Answer 1

Judging by the screenshot, you are trying to expand the disk to a size larger than the amount of free space.
Since this is not possible, the "next" button is disabled.
