Open the sketch containing the origin boring and set the pattern origin on the boring via button Pattern origin..

Via Generate sketch on selected face, create a new sketch for the pattern.

Note Set the sketch for the pattern points on the same plane as the sketch with the pattern origin.

In this sketch, set the starting point for the pattern design exactly at the same place, where the pattern origin is in the other sketch.

Select the point.

In 3D History, mark the design steps Cut extrude and the sketch, which contains the pattern (here in example Sketch 3) and in the context menu, click Create pattern.
