debian-live-12.1.0-amd64-gnome.iso로 만든 Debian 라이브 환경에서 쉘 스크립트를 실행할 수 없습니다.

디스크 A에 WinPE와 유사한 리눅스 생방송 환경을 만들고, , rootfs.tar.gz, 가 포함된 bzImageU 디스크 B를 Burning.shPC에 삽입하고 디스크 A를 이용하여 생방송 환경에 들어갔습니다. 그런데 지금은 Burning.sh라이브 환경에서 실행할 수 없는 것을 발견했고 , 오류는 다음과 같습니다.

bash: ./Burning.sh： cannot execute: required file not found.
