I want to install openSUSE tumbleweed by creating a bootable USB stick. Currently I have Ubuntu installed, so I have to create the USB stick from Ubuntu. The instructions here:
It’s the same instructions for live media or for the DVD installer (or the NET installer). At one time there were differences, but now the same method works for all.
If your USB is “/dev/sdX” then you should be able to use:
# dd if=iso-file of=/dev/sdX
Note that it is important to use “sdX” and not “sdX1” – the latter is a partition, but you should write to the entire device. The instructions say to use a large blocksize, which should speed things up.
You can possibly use
# ddrescue isofile /dev/sdX
That’s roughly what I do, except for opensuse it is “dd_rescue” while for Ubuntu, I seem to recall that it is “ddrescue”. Check the man page. I’m not sure if that is part of a standard Ubuntu install.
The advice about not using the live installer, is that recently the live media have been somewhat broken. For Leap 42.1, there isn’t an official live image, though there are some unofficial ones. I’ve mainly used the DVD installer, which I prefer to the live installers.
