          You are trying to perform very dangerous actions.

          Any mistake here may cost very high.

          You can lose your data.



          But please make sure that /dev/sdb exists.

          You can check all block devices with sudo lsblk and then continue using dd. Usually it is possible to write to the whole disk, not its partition (sdb instead of sdb1).



          In qemu part you should use the full path:
          sudo qemu-system-i386 /dev/sdb.
