how do i wipe my hard-drive and restore factory settings?

[sciencemouse]

i just got a new imac and thought i'd firewire from my old one, but doing this is set up after the intro video only let me register in my ex's name (who the older mac is registered to) - i obviously dont want this! how do i reset my imac so that i can register it without his name as the owner of the imac?!

The cleanest way is a reinstall of Mac os. This will wipe the drive of all information and give you your fresh factory settings.

how exactly do i do that? i assume there is more to just putting in the install disk - as that doesn't change anything?
