@Victor, You can't erase the data on the hard drive that you're running the OS on.

@lustring, Are you using the original CDs that came with your computer? The grey ones?

I was assuming that he had the OS X disc inserted.

I just meant if it was the reinstall CDs that came with the computer, or if he was using a retail copy.

0	have you heard of formating a drive then installing??? just a thought answered Oct 06 '10 at 19:31 Monkinto 721●8●13●21 Ever hear of being polite? (Oct 08 '10 at 21:23) Justin

0	Use the recovery disks that came with your computer. This is like performing a system recovery of sorts for Mac OS, cept it's better because you don't need a recovery point to carry it out. answered Oct 08 '10 at 21:57 Angelwork 561●36●37●50

-1	Does Disk Utility show a hard drive? If it does, it should allow you to erase the data. answered Oct 06 '10 at 18:03 Victor 2.0k●4●17●39
