I posted a problem here. Since this problem seems unknown or unheard I guess I have no other option to re-partition the hard drive and start fresh again to remove GRUB info in my Mac OS X. I hope this will help my problem. I want to make a nice copy of my hard drive to later on drop it in my system. I think I can do it this in Disk Utility by making the back up and restoring the image after I redo Partition and format while in Mac OS X install disk boot up. Am I correct?
