하드 디스크 오류로 인해 더 이상 부팅되지 않은 Ubuntu를 fsck로 오마화

이 중 HDD로 구축한 환경이 있었습니다만 떨어뜨리거나 낙하시키거나 하고 있었기 때문에 기동하지 않게 되어 버렸습니다.
키즈용으로는 HDD는 피하는 편이 좋을까? 우선 SSD나 USB 메모리로 환장할 때까지의 연결로서, 적당하게 오마화해 움직이게 했습니다.
단일 사용자 모드?
이런 경우 싱글 유저 모드로 fsck를 합니다만, Ubuntu에서는 어땠습니까?
여기까지 왔지만 여기에서 fsck를 부를 수 없었기 때문에 다른 USB 메모리에서 Ubuntu를 움직여 fsck 할 수 있도록 했습니다.
USB 메모리로 fsck
