Creating live USB

I’m coming back to openSUSE from Ubuntu, and I can’t believe that I’m getting stuck this early.

I’ve downloaded the 4.7GB DVD .iso, formatted the USB to ext4 (using the gui in Ubuntu, also tried FAT) and run:

sudo dd if=/home/david/opensuse/openSUSE131.iso of=/dev/sdc1

I’m booting to the USB and it’s giving me error: unknown filesystem, and then leaving me with the GRUB rescue prompt.

In the past I’ve used various GUIs to create live USBs, but I’m keen to figure out how to do so with the CLI. However, GUI suggestions also welcome.

And apologies if I’m overlooking some obvious documentation (I’ve seared but I can’t find anything that works).

Cheers.

You are following the instructions for a LIVE CD iso, but using a non-live DVD iso.

You might want to try this:
http://en.opensuse.org/Live_USB_stick#Put_ISO_on_vfat_partitioned_USB_stick_or_hard_disk

You are writing the .iso to the first partition of the USB, that won’t work!
You have to write it directly to the drive:

sudo dd if=/home/david/opensuse/openSUSE131.iso of=/dev/sdc

(provided it is sdc)

And it’s not necessary to format it before, since dd overwrites anything on the drive anyway…

This solution worked. I hadn’t ever had a think about what those device codes(?) (sdc, sdc1, sdc2 etc) are referring to, and now I do.

Thanks for the help!
