Because my OS X seems more instable than any Windows 95 installation i've ever worked with (macbook fresh). I want to reinstall all.. I did install bootcamp a while ago (damn, never should have do that, didn't use it, only caused trouble) so I need to remove that partition too... So... how do I work... Normally i would put in partionmagic do format all and put in cd... but guess my mac needs some other way... I don't need to save anything, just do a very very very clean install.
