GParted가 내 파티션을 망쳤습니다.

실제로 실행할 때 testdisk모든 파일을 볼 수 있습니다 /dev/sda1!

게임을 좀 할 수 있도록 데비안과 동시에 Windows를 설치하고 싶습니다. 이를 위해 Ubuntu Live 12.1 DVD를 부팅하고 GParted를 사용해야 했습니다(모든 것이 포함된 기본 파티션의 크기를 조정했습니다).

크기 조정이 성공적으로 완료되었습니다. 그런 다음 데이터를 백업하기 위해 데비안을 재부팅하려고 시도했지만 불행하게도 이전에 이 작업을 수행하는 것을 잊어버렸습니다.

GRUB는 잘 로드되지만 시스템이 제대로 부팅되지 않습니다! "ramdisk" 또는 이와 유사한 구성을 시도하면 프롬프트만 표시되고 그 이상은 아닙니다.

이제 우분투로 다시 부팅하고 축소된 파티션을 확인했습니다. 본질적으로 고장 났지만 오류 메시지를 실제로 이해할 수 없습니다.

GParted는 다음을 보고했습니다.

이것은 다음의 출력입니다 dmesg | tail.

파티션을 복구하는 방법은 무엇입니까? 내 데이터를 복구할 수 있나요?

내가 실행한 몇 가지 추가 명령은 다음과 같습니다.

sudo fsck.ext3 -cf /dev/sda1

파티션 테이블 항목에 "msdos"라고 표시되어 있습니다. 이렇게 되어야 합니까?
