If you are trying to save the hinges, the way I did it was to attach the hinges to the door, then stood the door up on blocks and shims at 90 degrees (perpendicular) to the wall. Swing the hinges open so they lie against the jamb. Be sure the door is plumb and level, at the correct height and correct distance from the jamb. Then I used the hinges as a template for marking where to chisel out the recesses in the jamb to accept the hinges. If the door is level and plumb it may stand by itself. If not, use tape to hold it in place long enough to draw the templates.
