Created attachment 717494 [details] bug1028369_data.txt I need help to continue investigation to understand why yast decides to move from initial_5 to initial_6 steps and displaying not expected "Disk Activation" screen, While before (at snapshot 20170304) yast moved from initial_5 to initial_7 steps directly displaying "Installation Mode" screen. The referenced data are accessible in attached bug1028369_data.txt
