wiping a mac hard drive.

self explanatory, i need soem help wiping my sisters mac HD. she fucked it up, and i wanna do a completely clean instalation.

K,
To wipe HD, either
a) Insert OS install CD #1 and hold down the "c" key, when you get to the installer, either write the new OS over, or click the Installer or sth name to the right of the apple button on the top left and click... I think it's disk utility, now select your drive and click the erase tab. Self explanatory from now on.
b) Rip out HD, place HD into Microwave, ?????, Profit!

To mop up the blatent fanboyism, Linux is good for somethings, OS X is good for some things. Get over it.
