In windows, go to control panel - system. Select the hardware tab, the select hardware profiles at the bottom. Listed here are your hardware profiles. There should be one for the bootcamp (default name "profile 1") and one for parallels configuration. Down below is a hardware profiles selection. You can set it to wait until a profile is selected or you can have it automatically boot into the first listed profile after a set time (i.e. 20 seconds or something). Just remember to set the one you want to boot automatically by setting the order. You'll see what I mean.
Hope this helps.
Updated! I forgot about the first dialog where you select the operating system. Maybe the other post will help you get past that and this post will help you get past the profile selection.
