New 
13.0.2a iso images have been released that fix the bug with the autoinstaller and hard drives bigger than 15GB that is mentioned in the first post. You can find those in the 
download page (link) and they should replace the 13.0.2 iso images. If you have already downloaded one of the 13.0.2 images and you don't want to do another download, just keep in mind to not use the 
autoinstall feature with hard drives bigger than 15GB and select the 
install option in the installer, which will let you specify any paritioning scheme using cfdisk.
