[opensuse] Checking installation media fails

Hi, I downloaded openSUSE Leap 42.2 DVD ISO and and created bootable flash: sudo dd if=/dev/zero of=/dev/sdb sudo fdisk -l # Ensure sdb is empty sudo dd if=openSUSE-Leap-42.2-DVD-x86_64.iso of=/dev/sdb Then I booted the flash disk, in the GRUB menu I selected 'More...' and 'Check Installation Media'. After while of processing I got blue screen with red warning saying 'This is not openSUSE Leap 42.2 medium!'. How can I verify, that the ISO was correctly transferred to the flash disk? I think this is bug of the checking system, because otherwise the medium works fine (rescue system as well as installation). -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux https://www.opensuse.org/ https://trapa.cz/
