Failed to boot using bootable flashdisk

Hi,

I want to install OpenSuse 41.2 Leap edition, I created bootable flashdisk using dd command using Ubuntu GNU/Linux.
But it failed while booting to usb. Please help me to fix it?

Follow the instructions here carefully

Explain to us what is happening when you say ‘Failed’
Is your target machine UEFI?

Did you do the dd to the device and not a partition on the device???

Not sure if it’s what OP is experiencing, but the current Net install media for Tumbleweed is broken for me. It crashes with a blank screen showing nothing but the text “signal 11” after booting, but before the installer launches. I used dd and verified the image was transferred correctly. I didn’t try the newest DVD install media, but last week’s install media works fine for me.
