Ubuntu 14.04를 설치했는데 이제 Windows가 부팅되지 않습니다.

Question

내 노트북에는 Windows 8.1이 사전 설치되어 있었습니다.

듀얼부팅을 설정했습니다. 모든 것이 괜찮아 보였고 OS를 선택하기 위해 메뉴에서 Ubuntu를 선택한 후 문제 없이 Ubuntu에 액세스했습니다. 부팅 방법이 레거시로 변경되었다는 점을 추가해야 합니다.

하지만 Ubuntu를 사용하면서 더 이상 OS를 선택할 수 없게 되었습니다. 노트북은 우분투로 바로 부팅됩니다.

따라서 복구 옵션에 액세스하려고 시도했지만 이제 Windows 8 복구 디스크를 사용하라는 지시를 받았기 때문에 Windows 8 부트로더가 어떻게든 손상된 것으로 나타납니다(이 디스크는 사전 설치되어 있으므로 가지고 있지 않습니다).

성공하지 못한 채 다시 부팅 복구를 시도했습니다. 재부팅할 때 Ubuntu, Memtest, Windows 8 Recovery 또는 Windows 8 Bootloader를 선택하라는 기본 시작 화면만 표시됩니다(부트로더를 사용하려면 다시 디스크를 삽입해야 합니다).

나는 시도했다

수동으로 아무것도 하지 않았습니다. 설치 프로그램이 모든 작업을 수행했습니다(다른 부트로더의 부팅을 허용하기 위해 부팅을 레거시로 변경하는 것을 제외하고).

Answer 1

해결됨

어떤 일이 일어났든 파일이 손상되었고 Live CD와 USB가 다른 컴퓨터에서 작동했음에도 불구하고 이 노트북은 디스크와 USB가 삽입되었음을 인식하는 것조차 거부하여 지옥 같은 Grub Recover에 직면하게 되었습니다.

다행히 저는 이 멋진 ASSIST 버튼이 있는 Sony Vaio를 사용하고 있었습니다. 이를 사용하려면 노트북을 완전히 끈 다음 전원 버튼을 누르는 대신 ASSIST 버튼을 누르기만 하면 됩니다. 그러면 Sony 복구 콘솔이 강제로 열립니다.

여기서는 OS 복구, HDD 점검 및 복구, BIOS 접속도 가능합니다.... 그래서 해봤습니다.

이전에 BIOS를 방문했을 때 Windows 8에 다른 OS를 설치하기 위해 부팅 옵션을 LEGACY로 변경했습니다. 따라서 이를 Legacy에서 UEFI로 다시 변경하고 부팅 순서를 다시 확인했습니다. 그런 다음 저장하고 다시 시작하면 이제 OS를 선택할 수 있는 옵션이 표시됩니다.

Answer 2

내 Windows 시스템은 레거시 모드에서 전혀 부팅되지 않습니다. Windows 8을 실행하려면 UEFI를 다시 켜야 한다고 생각합니다. 가능하다면 때때로 나에게 가장 적합한 UEFI/보안 부팅 없음 옵션이 있습니다.

GRUB를 직접 사용하는 대신 grub-customizer필요한 대부분의 작업을 처리하는 GRUB을 사용하고, 이 작업을 멋지고 쉬운 그래픽 인터페이스에서 수행하므로 제가 선호하는 옵션입니다. 그 중 하나는 HDD를 스캔하여 부팅 메뉴에 넣을 대체 OS를 찾는 것입니다. 이 프로그램을 받기 위한 지침을 찾을 수 있습니다.여기 우분투 포럼에서
