I have an iso file named output.iso with which I want to create a bootable usb.When I run the following command:sudo qemu-system-x86_64 -cdrom output.iso  I see that qemu manages to boot with it so I assume that the iso is OK.I copy the file to a usb with the following command:sudo dd if=output.iso of=/dev/sdb bs=4M; syncand then try to boot again with the following command:sudo qemu-system-x86_64 -hda \dev\usbbut now I get:No bootable device.Someone has an idea what am I doing wrong ?Thanks in advance....
Having some trouble creating a bootable usb
linux
sudo dd iflag=fullblock if=/path/to/iso of=/dev/sdx status=progressReplace /dev/sdx with your USB drive, e.g. /dev/sdb .and then:qemu -hda /dev/sdb Otherwise, recheck the ISO's hash
