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!'.
This has never worked with USB sticks. IMO, the installation program should check to see if the media is a real CD/DVD, and if not, abort.
This would be good. Current state is confusing...
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).
You verify only the downloaded ISO image.
The flash media doesn't need to be checked, same as you don't test a
Do You think so? There might be a problem. Same as You can verify CD after burning, but You can also check it from GRUB menu. And it makes sense to have such option. Also, USB sticks are not so reliable, so some problem may appear there during the time...
hard disk for a good copy. However, if you want, you can do a file compare. I'm unsure of the command to use for this: you have to compare the iso file to the raw device media, but limited to the exact number of bytes contained in the ISO (the size of the flash is not the same as the ISO).
I't be doable, but not so handy. One typically wishes to verify the stick before installation... -- Vojtěch Zeisek https://trapa.cz/
