Pop Os 운영 체제가 설치된 Lenovo Yoga 730C가 있습니다. 훌륭하게 작동하지만 외부 SSD에 또 다른 Pop Os가 설치되어 있고 부팅하려고 하면 Wi-Fi 옵션이 표시되지 않습니다. 인터넷에서 찾은 모든 정보에는 내 네트워크 카드가 지원되지 않을 수 있다는 내용이 나와 있지만 내 컴퓨터 SSD에서 설치한 Pop Os는 제대로 작동했지만 외부 SSD에서는 작동하지 않았습니다. 예전에는 훌륭하게 작동했지만 다른 외부 SSD 중 하나를 테스트하기 위해 레거시 부팅을 활성화했을 때 모든 것이 바뀌었습니다. 이전 부팅을 끈 후에도 Wi-Fi 옵션이 없다는 문제가 계속 지속되었습니다.
