인터넷에 연결할 수 없거나 기본 게이트웨이를 ping할 수 없는 이유는 무엇입니까?

인터넷에 연결할 수 없거나 기본 게이트웨이를 ping할 수 없는 이유는 무엇입니까?

내가 시도한 것:

내 컴퓨터에 여분의 하드 드라이브가 있고 Linux Mint(20.2 cinnamon 64비트)가 설치되어 있습니다. 이제 Windows(주 OS) 또는 Mint로 부팅할 수 있습니다. 새로 설치한 후에는 쉽게 인터넷에 연결할 수 있고 시스템 업데이트를 완벽하게 다운로드하여 설치할 수 있습니다. 설정을 마치고 윈도우에서 잠시 게임을 해봤습니다. Mint를 다시 시작하면 인터넷에 접속할 수 없습니다. 저는 Google을 통해 전통적인 방식으로 이 문제를 해결하려고 시도했지만 성공하지 못했습니다. 새로 설치하는 동안 찍은 스냅샷에서 복원도 시도했습니다. 하지만 내가 시도한 어떤 것도 온라인에 접속할 수 없습니다.

현재 구성 및 유용한(희망적으로) 출력:

답변1

대답은 다음과 같습니다 ...

  1. BIOS로 부팅

  2. Linux Mint의 HDD를 가장 높은 부팅 우선순위로 설정하세요

  3. 컴퓨터 전원을 끄세요

  4. Linux로 직접 부팅

  5. 행복한 구성

(아마도 Windows 드라이버는 전원이 껐다 켜질 때까지 하드웨어 제어권을 완전히 포기하지 않기 때문에 Linux를 재부팅해도 작동하지 않을 것 같습니다.)
