    I just used dd to copy over the Tumbleweed image from 7/27/2015 to a USB key, and now, again, my USB key will not show up as a UEFI drive. It looks as though this snapshot is also broken. Can someone confirm please?

    I downloaded the live rescue CD, and it is broken. It didn't seem worth the trouble of downloading the full DVD image, when the rescue CD image is already broken. The tools/scripts/whatever that they are using to generate these isos appear to be in need of repair.

    Tried the 7/28/2015 snapshot and it's still broken. I also tried using mksusecd again with the 7/27/2015 ISO image and that resulted in a bunch of checksum failures right away in YaST.

    I already tried the rescue CD for 20150728. And it, too, is broken.

    I download snapshot openSUSE-Tumbleweed-NET-x86_64-Snapshot20150728-Media.iso, still doesn't work.

    I tried mksusecd again and this time had success with the 20150728 snapshot. I installed Tumbleweed in UEFI mode without any problems. To recap, mksusecd did successfully write an ISO and I was able to boot the Tumbleweed snapshot in UEFI mode, but then in YaST got inundated with checksum errors popping up. Another time the installation failed very early on in the process and YaST dumped me into the ncurses blue screen which provides the user with a few options, such as "reboot". You can easily add the repo by searching for this software title at https://software.opensuse.org/. I can't say why it didn't work the first few times but I did reformat and reinstall everything, including mksusecd. Maybe in its current state the program can be hit or miss.

    I tried "mksusecd" on the live rescue CD image. It seemed to complete successfully, but said that there was something weird about the first partition. But then I looked, and still could not see an EFI partition.

    Incidentally, I installed "mksusecd" in an existing Tumbleweed (from the repos) and ran it there.

    My tentative plan for my next install is to switch to legacy mode in the BIOS, install that way, then later switch it to UEFI mode. I've been meaning to test how well that works. But then maybe the problem will be fixed by then.

    I cannot test it because OVMF boots this ISO image both as CD and HDD.
