It appears that your HDD is spinning up in time to boot properly especially
since the workaround you have now solves the problem since the time required
to check for a DVD is enough to get the HDD up to speed.
If you put a non bootable disk in your DVD drive it may still delay it long
enough and not ask you if you want to boot.
If you do a restore will the system boot without any disk in the DVD drive?
If yes then it is because the HDD is already powered on.
