Windows 7과 Ubuntu를 이중 부팅하도록 컴퓨터를 설정하려고 합니다. Windows 7을 먼저 설치했는데 모든 것이 괜찮아 보였습니다. Ubuntu 10.04를 설치했습니다(많은 사람들이 나에게 언급한 Unity가 기본적으로 설치되는 것을 방지하기 위해 짜증나는 일입니다).
이제 grub 메뉴에서 Windows 7을 선택하면 단순히 빈 화면이 나타나고 grub 메뉴로 돌아갑니다.
다음은 부팅 정보 스크립트의 결과입니다. testdisk를 실행하고 Windows 부팅 섹터를 확인해 보았습니다. 부팅 섹터와 백업 부팅 섹터가 모두 정상이며 서로 일치한다고 표시됩니다.
그러나 Windows 부팅 섹터가 괜찮다면 왜 일반적인 "체인로더 +1" 접근 방식이 작동하지 않을까요??
유사한 문제에 대해 포럼을 확인해 보았지만 대부분 실수로 MBR 대신 Windows 파티션에 grub을 설치한 사람들인 것 같습니다. bootinfo 스크립트 결과에 따르면 여기서는 특별한 실수를 하지 않았습니다.

답변1
Windows에 최대 절전 모드 또는 chkdsk 필요와 같은 문제가 있는 경우 grub에서 부팅되지 않는 경우가 많습니다.
Ubuntu 설치 프로그램에서 크기를 조정한 경우 chkdsk가 수행하는 Windows 부팅 섹터 복구가 필요합니다. 그러나 Windows 또는 Windows 복구 CD에서만 chkdsk를 실행할 수 있습니다.
몇몇은 grub 부팅에서 f8을 사용할 수 있었지만 속도가 너무 빨라 일반적으로 작동하지 않습니다. Windows 복구 CD가 없는 경우 chkdsk를 실행할 수 있는 타사 Windows 도구도 있습니다. 설치한 모든 시스템의 현재 버전에 대한 복구 도구 CD 또는 플래시 드라이브가 있어야 합니다.
또한 무료 버전에는 chkdsk 및 기타 Windows 복구 기능이 있습니다.

Hiren의 부팅 CD에서 chkdsk를 실행할 수 있습니다. (미니 XP.) Hiren의 부팅 CD를 넣고 XP에서 chkdsk를 수행합니다.
