vista win7 dual boot

I started out with Vista 32 Ultimate installed on my machine. I created a second partition on that system drive , and left my data drive alone and installed Win 7 64 Ultimate RC on the new partition. The system boots to win7 with no boot menu to pick vista from, any ideas?

You can use EasyBCD to recreate your boot menu:

It's really easy to use and should let you pick between Vista and Windows 7 each time you boot

I had this problem too try this:
Put your install disk back in and click on repair and not the Install button when it comes up... go through this procedure and hey presto when you next boot up there will be the boot menue
