I just finished a "clean" install of Snow Leopard, and guess what? My "clean" install didn't work. After the "installation" was "finished", my Mac booted back into my old partition.

Going to try again, but this time use Disc Utility to erase the Mac OS X partition.


Any ideas what went wrong? (new virus?????)

Thanks.
 
If you created a new partition, it will still default to the old one, so you have to change the startup disk in system prefs. If you just tried to reinstall, that just reinstalls the OS, but leaves everything else there. You have to erase the partition, then install, and that will be fresh.
