I have a Carbon Copy Cloner image and yesterday I installed Boot Camp to install Windows XP, but something went wrong with Boot Camp and it destroyed my Snow Leopard install and my iMac refused to load. So I then booted my external USB Hard drive and cloned the USB Hard drive CCC image back onto the Macintosh internal HD, but when it went to boot it said something about unable to boot. I then had to install the Snow Leopard installation DVD to get the iMac to boot properly and then clone the external CCC image back onto the internal Macintosh HD. But WHY did CCC fail to fix the boot sectors or whatever is needed to properly boot the iMac? So CCC doesn't backup and resore all the proper boot sectors to properly boot the iMac? What did the proper Snow Leopard install DVD that CCC failed to do?
