I have had the same problems over the years since the 7.1 days with the 'Boot To Production' task. I have stated my opinions with Symantec front-end and back-end people; hopefully they will fix it to perfection one day. What I like about it, when it works is if you boot to production, you over ride anything in you bios' boot order. So boot to pxe > you will boot to pxe no matter if your boot order is set to boot to your hdd first. The opposite with boot to production.
My alternative is to use a script the uses shutdonw.exe -r -t 00.
