Reformat XP for Vista Help

[Yggoir]

I built a new computer last summer with a 320 Seagate hardrive. I got a orignal verison of Windows XP off of ebay when installed it only saw around 130gb of the hardrive. I am wanting to completely reformat to install Vista.

What is the best way for me to format so I will get my whole hardrive?

During the install, delete the partition and allow it to be re-created.
