Uninstall Windows XP and keep Vista - HP dv8320us

[sandesign]

Hi to everyone,

I'm new to the forum. My first question is about a dual boot machine. It's a HP Pavilion dv8320us notebook that came with Windows XP Media Center Edition 2005. I purchased Windows Vista Home Premium about 3 months ago and I love it . I did a dual boot with the two systems with no problem. Vista has been great, all my programs work perfectly (faster than XP) and i'ts very fast. Since i did the dual boot installation I haven't booted to XP, so I don't need it anymore.

What's the best way to get rid of XP and keep only Vista?

Thanks for the help...

PS: sorry for my english...
