Description of problem:
error occurs when trying install F20 i386 to new notebook (which come with Linpus Linux preinstalled), using kickstart file without partitionning stuff. It appers almost immediately after anaconda was started. IMO it is same error which I stretch several times before, and occurs when system HDD is always partitioned before anaconda start.

Version-Release number of selected component:
anaconda-20.25.15-1
