HP Pavilion dv9700

The laptop came with Vista on the first drive. I purchased a second on end installed XP. I have found almost all the drivers and XP is working fine. Within the disk management of one drive and can see the other drive. When I put up I don't get an option to choose which OS to load. It is automatically loading XP, the os I just installed on the second drive. Any ideas?

When setting up a dual boot system, the older operating system must be installed first and then the newer operating system.

Because you have installed XP after Vista, XP has replaced the bootloader and it does not recognize Vista anymore.

Read here about how to possibly restore the Vista bootloader.
