Something like this ?

(defun minibuffer-select-inital-input ()
  (let ((start (next-single-char-property-change 1 'read-only)))
    (when (< start (point-max))
      (set-mark start)
      (setq mark-active t))))

(add-hook 'minibuffer-setup-hook 'minibuffer-select-inital-input)
(read-string "> " "Hallo")
