Bootable usb image

Because of problems to boot and install RancherOS from usb stick with the rancher.iso (dd to usb stick) and also ipxe isn’t working (seems to be an dns issue?)…

Is there a usb stick boot image available? Or how could build a bootable usb stick with the rancher iso?

Solved it with iPXE boot.
