#질문

안녕하세요. 우분투 부팅이 안되는데 어떻게 해야될지 아무리 찾아봐도 모르겠어서 이곳에 찾아왔습니다.

현재 다음과 같은 에러가 발생하며 부팅이 안됩니다.

grub에 접속

```auto
set root=(lvm/vg1-lv—0)
linux /vmlinuz-5.15.0-97-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro
initrd /initrd.img-5.15.0-97-generic
boot

```

이렇게 부팅 하여서  
docker를 start 해도

다음과 같은 에러가 발생하며 도커 로그인이 안됩니다.  
ssh 연결, .1.1.1.1 ping 등 나머진 다 작동합니다.

제가 우분투에 대해 잘 몰라서  
제 나름 시도했을때 사진찍어뒀던 모든 사진을 순서 상관없이 올립니다.  
도와주세요…

여기서 글쓴분과 비슷한 현상이 있네요.  
Had a very similar issue after an update of Ubuntu 20.04 on a Dell XPS13 (2020). Searched for hours, the solution was actually super easy.

reboot and go to BIOS using “fn and F2” BIOS \> System Configuration \> Sata Operation \> switch to “AHCI” from “RAID On”

For some reason this BIOS settings was switched.

한번 시도해보세요 🙂
