I downloaded an iAtkos v7 iso and burned it at 4x speed.

I booted it up and installed it on an 80GB MAC OSX Extended Hard Drive. Now when I try to boot up, it shows the apple logo and after about a minute, a small stop sign shows up.

It looks like this, the small image - http://www.psdgraphics.com/wp-conten...not-symbol.jpg

I booted up the installation CD and tried to repair the HDD but it said it was ok.
