Hi Guys, thanks for everyone's help and for all your suggestions. Nothing I tried got ride of the dual boot at startup though. I am assuming this is because when I installed Vista it didn't format my drive. You have to go into Advanced options when installing Vista and specify that you want the drive formatted during installation.
In any case, I formatted my drive with a Partition Manager boot Disc, and reloaded Vista. I am good to go now.
Cheers!
Andrew
